Correct Answer: D

Rationale: Administering a prescribed diuretic is the most important intervention in this scenario as the client is presenting signs of fluid overload and heart failure. Diuretics help reduce fluid retention in the body, alleviating symptoms like edema and crackles. Restricting fluid intake may be necessary in some cases, but in this acute situation, addressing the immediate fluid overload with a diuretic takes precedence. Weighing the client daily and maintaining accurate intake and output are important aspects of monitoring, but they do not directly address the urgent need to manage fluid overload.

Correct Answer: D

Rationale: The correct answer is D. The moist cough that worsens during and after meals suggests possible dysphagia, a condition related to swallowing difficulties. Requesting a consultation for dysphagia is essential for an accurate diagnosis and appropriate management. Encouraging the client to perform deep breathing exercises (choice A) may not address the underlying issue of dysphagia. Offering additional clear fluids (choice B) may not be appropriate for someone with swallowing difficulties. Collecting a sputum specimen (choice C) is not the priority in this scenario as the focus should be on identifying and managing the swallowing problem.

Correct Answer: A

Rationale: The vastus lateralis is the preferred site for IM injections in infants due to their limited muscle mass and safety. Infants do not have well-developed muscle mass, making the vastus lateralis the best option for IM injections. The deltoid muscle is typically used for older children and adults. Ventrogluteal and dorsogluteal sites are not recommended for infants due to safety concerns, including the risk of damaging the sciatic nerve. Therefore, the correct choice is the vastus lateralis for IM injections in infants.

Correct Answer: A

Rationale: To calculate the total dose of baclofen needed in a 24-hour period, multiply 15 mg by 3 doses, which equals 45 mg. Since the tablets are available in 10 mg strength, divide the total dose needed (45 mg) by the strength of each tablet (10 mg), which equals 4.5 tablets. Rounding off to the nearest tenth, the nurse should administer 4.5 tablets of 10 mg baclofen per day. Therefore, choice A is correct. Choices B, C, and D are irrelevant as they are not provided.

Correct Answer: C

Rationale: In a client with acute adrenal insufficiency (Addisonian crisis) following a motor vehicle collision, the priority intervention is to administer IV corticosteroid replacement. This is crucial to manage the crisis by replacing the deficient cortisol. Determining serum glucose levels (Choice A) may be important but is not the immediate priority in this situation. Withholding potassium additives to IV fluids (Choice B) is not indicated and may exacerbate electrolyte imbalances. Initiating IV vasopressors (Choice D) is not the primary treatment for acute adrenal insufficiency and should be reserved for managing hypotension that is unresponsive to corticosteroid therapy.
