1. The nurse is preparing to administer an intramuscular injection to a client with muscle wasting in the gluteal region. What is the most appropriate site for the injection?

Correct answer: D

Rationale: The vastus lateralis site is the most appropriate for an IM injection in a client with muscle wasting in the gluteal region. Administering the injection in the vastus lateralis ensures effective medication delivery due to muscle wasting in the gluteal region, preventing potential complications associated with the dorsogluteal or ventrogluteal sites, which may not be suitable in this specific client case. The deltoid site is mainly used for smaller volumes of medication and may not be ideal for this scenario.

2. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

Correct answer: D

Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.

3. An older female client tells the nurse that her muscles have gradually been getting weaker. What is the best initial response by the nurse?

Correct answer: D

Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.

4. A client with a history of chronic kidney disease (CKD) is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in patients with CKD because contrast agents can potentially worsen kidney function and lead to contrast-induced nephropathy. Monitoring serum creatinine helps assess kidney function and determine the risk of complications. Choices B, C, and D are less relevant in this scenario. Blood urea nitrogen (BUN) is another marker of kidney function, but serum creatinine is a more specific indicator. Serum potassium levels are important in assessing electrolyte balance but are not directly related to the risk of contrast-induced nephropathy. Serum glucose levels are not typically a primary concern before a CT scan with contrast in a patient with CKD.

5. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?

Correct answer: A

Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.
