Correct Answer: C

Rationale: Verifying the client's identity with two nurses before starting the transfusion is a critical safety measure to prevent transfusion errors, such as administering blood to the wrong client, which can lead to severe complications like hemolytic reactions.
Choice A is wrong because checking the client's temperature 1 hour after the transfusion is not a standard requirement; temperature should be monitored before, during (especially the first 15 minutes), and at the completion of the transfusion to detect febrile reactions.
Choice B is wrong because infusing packed RBCs over 6 hours exceeds the recommended time frame (typically 2-4 hours) and increases the risk of bacterial contamination or hemolysis.
Choice D is wrong because administering a diuretic prior to the transfusion is not routinely indicated unless the client has a specific condition like heart failure or fluid overload, which would be determined by the provider.

Correct Answer: C

Rationale: Monitoring for signs of infection is critical, as prednisone, a corticosteroid, suppresses the immune system, increasing infection risk in clients with adrenal insufficiency.
Choice A is incorrect because prednisone should be taken with food to reduce gastrointestinal irritation, not on an empty stomach.
Choice B is incorrect because prednisone for adrenal insufficiency is typically a lifelong therapy, not limited to a few weeks.
Choice D is incorrect because reducing the dose without medical guidance can precipitate an adrenal crisis; dose adjustments must be supervised by the provider.

Correct Answer: A

Rationale: A non-tender, protruding abdomen is a normal finding for a 2-year-old toddler. This is due to the immature development of the abdominal muscles and the relatively large size of the liver and kidneys in relation to the rest of the body.
Choice B is wrong because the head circumference should be equal to or less than the chest circumference by age 2. A head circumference that exceeds the chest circumference could indicate hydrocephalus or other neurological problems.
Choice C is wrong because the fontanels, or soft spots on the skull, should be closed by the age of 18 months. Palpable fontanels could indicate dehydration, malnutrition, or congenital disorders.
Choice D is wrong because the natural loss of deciduous teeth, or baby teeth, usually begins around age 6. Premature loss of teeth could indicate dental caries, trauma, or endocrine disorders.

Correct Answer: C

Rationale: Storing insulin detemir at room temperature for up to 42 days maintains potency. Shaking is incorrect, it's not taken before meals, and it's clear.

Correct Answer: A

Rationale: Avoiding all products containing alcohol, including mouthwash, is critical with disulfiram, as it causes a severe reaction (flushing, nausea, vomiting) when alcohol is consumed, deterring alcohol use.
Choice B is incorrect because disulfiram is typically taken at bedtime to minimize side effects like drowsiness, not in the morning.
Choice C is incorrect because a metallic taste is not a common side effect of disulfiram; it is more associated with metronidazole.
Choice D is incorrect because disulfiram should not be discontinued abruptly without provider guidance, even if drinking resumes, to avoid complications.
