Correct Answer: D

Rationale: The correct way to collect a 24-hour urine specimen is to discard the first morning void and then start the collection. Choice A is incorrect because refrigeration is not typically necessary for a 24-hour urine specimen. Choice B is incorrect as the client needs to discard the first void. Choice C is incorrect; while collecting urine for 24 hours is correct, keeping it on ice is not standard procedure.

Correct Answer: D

Rationale: The correct answer is D. When assessing a client diagnosed with a brain tumor, asking about seizures is crucial because they can be a common symptom associated with brain tumors. Seizures in this context could provide valuable information regarding the progression and impact of the brain tumor on the client's neurological status. Choices A, B, and C are important questions in a general assessment, but when specifically focusing on a client with a brain tumor, inquiring about seizures takes priority due to its direct relevance to the condition.

Correct Answer: C

Rationale: Administering the scheduled dose of furosemide is appropriate when a client with heart failure has an elevated BNP level. BNP elevation indicates fluid overload, and furosemide is a diuretic that helps in reducing excess fluid. Measuring the client's oxygen saturation (Choice A) is not directly related to addressing fluid overload. Administering nitroglycerin (Choice B) is not indicated for managing elevated BNP levels. Holding the furosemide dose (Choice D) would delay appropriate treatment for fluid overload.

Correct Answer: C

Rationale: The correct answer is C: Select a large, deep muscle mass. When administering an intramuscular injection with a painful medication volume of 3 ml, selecting a large and deep muscle mass is crucial. This intervention reduces discomfort for the patient and ensures proper absorption of the medication. Choice A is incorrect because instilling the medication quickly can increase discomfort. Choice B is incorrect as inserting the needle slowly may prolong the discomfort. Choice D is incorrect as using a short, small gauge needle may not be suitable for delivering 3 ml of medication effectively into the muscle.

Correct Answer: C

Rationale: When a nurse observes periods of apnea in a client experiencing Cheyne-Stokes respirations, measuring the length of the apneic periods is essential. This action helps in determining the severity of Cheyne-Stokes respirations by providing valuable information about the duration of interrupted breathing cycles. Elevating the head of the client's bed (Choice A) may be beneficial in some respiratory conditions but is not the priority in Cheyne-Stokes respirations. Auscultating the client's breath sounds (Choice B) is a general assessment and may not directly address the issue of apnea in Cheyne-Stokes respirations. Suctioning the client's oropharynx (Choice D) is not the initial intervention for managing Cheyne-Stokes respirations unless secretions are obstructing the airway.
