Correct Answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

Correct Answer: D

Rationale: When caring for a client receiving brachytherapy, it is crucial to handle radioactive sources appropriately. Discarding the radioactive source in a biohazard bag is essential to prevent exposure to radiation. Cleaning equipment before removal, limiting client's visitors, or discarding linens in a double bag are not specific to the management of radioactive sources in brachytherapy.

Correct Answer: B

Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.

Correct Answer: A

Rationale: Individuals with obsessive-compulsive disorder often feel compelled to perform rituals to alleviate anxiety. Allowing the client enough time to perform these rituals can help reduce their anxiety levels and promote a sense of control. Providing autonomy in scheduling activities can also empower the client and enhance their sense of independence. Discouraging exploration of irrational fears may increase anxiety and worsen symptoms. Negative reinforcement for ritualistic behaviors is not recommended as it can be counterproductive and reinforce the behavior.

Correct Answer: C

Rationale: Educating the client on the importance of rising slowly when getting out of bed is crucial due to the risk of orthostatic hypotension associated with furosemide use. This precaution helps prevent dizziness and falls. Options A and D are incorrect as furosemide commonly causes hypokalemia and dehydration, respectively, rather than high potassium levels or overhydration. Option B is inaccurate as clients on furosemide need to reduce sodium intake to manage fluid retention.
