Correct Answer: B

Rationale: Assessing blood pressure is the priority assessment when working with a population of African-American clients due to the high prevalence of hypertension in this group. African Americans have a higher risk of hypertension, which can lead to complications like end-stage renal disease. Monitoring blood pressure allows for the early detection and management of hypertension. While measuring height and weight, observing for signs of abuse, and asking about medications are important assessments, assessing blood pressure is crucial in this context to address the specific health needs of African-American clients.

Correct Answer: A

Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.

Correct Answer: B

Rationale: After intermittent bolus feedings through a nasogastric tube, the correct position for the client is to keep the head of the bed flat. This position helps prevent vomiting and aspiration. Placing the client in a supine position (choice A) can increase the risk of aspiration. The left lateral position (choice C) is not typically used after nasogastric tube feedings. Elevating the head of the bed 30 to 45 degrees (choice D) is suitable for continuous tube feedings to reduce the risk of aspiration, but for intermittent bolus feedings, keeping the head of the bed flat is preferred to prevent regurgitation and aspiration.

Correct Answer: B

Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.

Correct Answer: D

Rationale: The correct answer is D: "395 units/L." The normal serum amylase range is 25 to 151 units/L. In acute pancreatitis, the amylase level is greatly increased, typically exceeding the upper limit of the normal range. Choices A, B, and C fall within the normal range of serum amylase levels and would not be expected in a client with acute pancreatitis.
