1. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:

Correct answer: it is chemically stable, nonallergenic, and can be administered orally once a day.

Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.

2. The test used to differentiate sickle cell trait from sickle cell disease is:

Correct answer: Hemoglobin electrophoresis

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

3. High uric acid levels can develop in clients who are receiving chemotherapy. This can be caused by:

Correct answer: rapid cell catabolism.

Rationale: The correct answer is 'rapid cell catabolism.' During chemotherapy, rapid cell destruction occurs, leading to an increase in uric acid levels as a byproduct of cell breakdown. High uric acid levels are primarily a result of the rapid breakdown of cells during chemotherapy, not due to the kidneys' inability to excrete drug metabolites (Choice A). The prophylactic antibiotics given concurrently do not directly cause high uric acid levels (Choice C). The altered blood pH from the acidic nature of the drugs (Choice D) is not a direct cause of elevated uric acid levels; the main mechanism is the rapid cell catabolism that occurs during chemotherapy.

4. Following an automobile accident that caused a head injury to an adult client, the nurse observes that the client sleeps for long periods of time. The nurse determines that the client has experienced injury to the:

Correct answer: hypothalamus.

Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

5. When teaching clients with a diagnosis of Schizophrenia nearing discharge from a residential care facility, what is an essential topic to include?

Correct answer: how to recognize and manage symptoms of relapse.

Rationale: When educating clients with Schizophrenia nearing discharge, it is crucial to focus on teaching them how to recognize and manage symptoms of relapse. Clients are usually aware of these symptoms, such as feeling anxious and overwhelmed, before the onset of psychosis. This early stage is vital for intervention, which involves finding a safe environment, seeking help, avoiding stressors, and reducing stimuli. Understanding and managing relapse symptoms empower clients to take proactive steps in their care. Choices A and C are not as immediate and practical as recognizing symptoms of relapse for client safety and well-being. While contact with follow-up care is important, it is not as urgent and specific as knowing how to manage relapse symptoms for immediate intervention.
