Nursing ANCC Adult Health Clinical Nurse Specialist Certification (ACNS) Sample Questions (Q184-Q189):
NEW QUESTION # 184
The Adult Clinical Nurse Specialist is seeing a 66-year old woman with well controlled hypertension. She finds that this patient is taking hydrochlorothiazide and has ad a 3 day history of a unilateral throbbing headache. She cannot chew because it increases the pain. Her physically exam is unremarkable except for a tender, incompressible right temporal artery. Her vital signs are normal. What is her diagnosis?
Answer: B
Explanation:
The correct diagnosis for the patient described is giant cell arteritis (GCA), also known as temporal arteritis. This condition is an important consideration due to the patient's age, symptoms, and examination findings. Giant cell arteritis is a form of vasculitis that predominantly affects older adults, typically those over the age of 50.
The key symptoms prompting consideration of GCA in this patient include a new, unilateral, throbbing headache and pain upon chewing (jaw claudication). These symptoms reflect the typical inflammatory process associated with GCA that affects the blood vessels supplying the scalp and muscles involved in mastication. The tenderness and incompressibility of the temporal artery on physical examination are classic signs of this disease. These physical signs are indicative of inflammation and possible thickening of the arterial walls, which can be palpable as a tender, hardened, or cord-like structure along the temple.
Additionally, while the patient's hypertension is well-controlled and might not directly relate to her current symptoms, it's important to consider that systemic vascular issues are more prevalent in patients with long-term hypertension. This background could indirectly increase the susceptibility or mask some symptoms of vascular inflammatory conditions like GCA.
The importance of timely diagnosis and treatment of giant cell arteritis cannot be overstated. If left untreated, GCA can lead to serious complications such as irreversible vision loss due to involvement of the arteries that supply the optic nerve. The typical treatment involves high-dose corticosteroids, which can significantly alleviate symptoms and prevent complications if started early.
In conclusion, the symptoms of a persistent, severe headache localized to one side of the head, jaw pain during mastication, and a tender, incompressible temporal artery in an elderly patient strongly point towards a diagnosis of giant cell arteritis. Immediate further investigation, typically including blood tests like the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), and potentially a temporal artery biopsy, is warranted to confirm the diagnosis and commence appropriate treatment.
NEW QUESTION # 185
Which type of formulation is most commonly used to fulfill nutritional needs of patients?
Answer: D
Explanation:
The correct answer to the question of which type of formulation is most commonly used to fulfill the nutritional needs of patients is "Isotonic polymeric." This type of formulation is widely used because it is generally sufficient to meet the basic dietary requirements of most patients who require nutritional support. Isotonic polymeric formulas are balanced in osmolarity with the human body, which helps minimize the risk of fluid imbalances and ensures that nutrients are delivered in a form that is easy for the body to absorb and utilize.
Isotonic polymeric formulas are composed of complete proteins, carbohydrates, fats, vitamins, and minerals in a form that is close to the natural composition of a balanced diet. The isotonic nature of these solutions means that they have the same osmotic pressure as blood and other bodily fluids, which facilitates easier absorption through the gastrointestinal tract and reduces the likelihood of osmotic diarrhea.
In contrast, elemental formulations are used in more specific medical scenarios. These are typically prescribed for patients who have severe digestive or absorptive issues, such as those with compromised function of the small bowel. Elemental formulations contain nutrients in their simplest form, often amino acids, glucose, and lipids, which require minimal digestion and are directly absorbed into the bloodstream. These are particularly helpful for patients with conditions like severe malabsorption, inflammatory bowel disease, or short bowel syndrome.
Thus, while isotonic polymeric formulations are the standard choice for general nutritional support in clinical settings, elemental and other specialized formulations are reserved for specific clinical indications where more tailored nutritional solutions are necessary to manage unique health concerns. This nuanced approach ensures that all patients receive the most appropriate type of nutritional support according to their individual health needs.
NEW QUESTION # 186
Which of the following is NOT a risk of autotransfusion?
Answer: B
Explanation:
*Autotransfusion is a medical procedure where a person receives their own blood for a transfusion instead of banked donor blood. This technique is often used during surgeries where there is a high expectation of blood loss, such as in cardiac or orthopedic surgeries. Autotransfusion can be advantageous because it minimizes the risk of transfusion-related infections and immune reactions since the blood used is the patient's own. *
*One of the major risks associated with autotransfusion is sepsis, particularly if the blood collection or handling procedures are not properly sterilized. Since the blood is collected during surgery, it must be done so in a sterile manner to avoid contamination with bacteria or other pathogens that could cause an infection when reinfused. *
*Another risk involves air embolism, which can occur if air accidentally enters the veins during the transfusion process. This can be life-threatening if not immediately managed, as it can obstruct blood flow to vital organs. *
*Regarding the risk of citrate toxicity, this primarily concerns the anticoagulant used in stored blood to prevent clotting. In most autotransfusion systems, citrate is also used as an anticoagulant. However, because the blood is typically reinfused quickly after collection, the body's natural mechanisms can efficiently metabolize the citrate, generally reducing the risk of toxicity compared to traditional blood transfusions where blood may have been stored for longer periods. *
*Lastly, transfusion reactions in autotransfusion are significantly less likely compared to donor blood transfusions. This is because the blood reinfused is the patient's own, which eliminates the risks associated with immune system reactions to foreign blood antigens. While not entirely impossible (particularly if the blood is mishandled or contaminated), the risk of a transfusion reaction in the context of using one's own blood is minimal. *
*Therefore, the correct answer to the question, "Which of the following is NOT a risk of autotransfusion?" is "Transfusion reaction." This is because, in autotransfusion, the use of the patient's own blood significantly diminishes the risk of an immune response compared to the transfusion of blood from another donor.
NEW QUESTION # 187
An SpO2 reading is taken by which of the following?
Answer: D
Explanation:
An SpO2 reading, which stands for peripheral capillary oxygen saturation, is primarily taken using a device called a pulse oximeter. This non-invasive tool is used widely in the medical field to monitor the oxygen saturation level of a patient's blood. This is crucial in determining how well oxygen is being sent to parts of the patient's body furthest from the heart.
To understand how a pulse oximeter works, it's important to know that it uses light-emitting diodes projecting light through a relatively transparent area of the patient's body, usually a fingertip or earlobe. It then measures the amount of light absorption by oxygenated and deoxygenated hemoglobin in the blood, using this data to calculate the SpO2 level. The reading is presented as a percentage, with normal levels typically between 95 to 99 percent, indicating that almost all of the hemoglobin is saturated with oxygen.
This method of measuring oxygen saturation is different from the measurement of arterial oxygen saturation (SaO2) which is obtained through an arterial blood gas test. An arterial blood gas test is more invasive, requiring a blood sample to be drawn from an artery. It provides a more precise measurement of oxygen saturation and can give additional information about carbon dioxide levels and blood pH, which are critical in managing certain medical conditions.
Returning to the options provided in the question a capnometer and a capnographer are devices used to measure the amount of carbon dioxide in exhaled air and are not used for measuring SpO2. An EGG, likely a typo for ECG (electrocardiogram), is a test that measures the electrical activity of the heart and also does not measure SpO2. Therefore, the correct answer for the tool that takes an SpO2 reading is the pulse oximeter, distinguishing it from the other devices mentioned.
NEW QUESTION # 188
Which of the following would NOT be a question you would ask during a patient's cultural assessment?
Answer: C
Explanation:
A cultural assessment in healthcare settings is a critical component of understanding a patient's background, which includes their social practices, language, norms, and values that could influence their health behaviors and outcomes. The purpose of conducting a cultural assessment is to obtain insights that enable healthcare providers to deliver culturally competent care, which takes into account the patient's beliefs, practices, and cultural needs.
Questions typically asked during a cultural assessment focus on areas such as the patient's ethnicity, religious beliefs, family dynamics, dietary habits, and daily routines. For example, asking about the number of people living in a household can provide information on the patient's living conditions and social support, which are relevant to their health and well-being. Inquiring about daily routines helps in understanding the patient's lifestyle, which might include physical activity levels or exposure to stress. Questions about dietary habits are also relevant as they provide insights into possible nutritional deficiencies or culturally specific foods that might impact health conditions like diabetes or heart disease.
On the other hand, asking a patient if they have medical insurance, while undoubtedly important for logistical and billing purposes, does not contribute to understanding their cultural background. Insurance-related questions are primarily administrative and are aimed at facilitating the payment process and determining eligibility for certain medical services. These questions do not provide insights into how cultural factors influence the patient's health or how healthcare should be tailored to meet their cultural needs.
Therefore, in the context of a cultural assessment, the correct answer to the question about what would NOT be typically asked is "Do you have medical insurance?" This question is unrelated to the cultural factors that the assessment aims to uncover. While it's an essential part of the overall patient intake process, it does not contribute directly to understanding the cultural aspects that might affect a patient's health care and outcomes.
