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

Correct answer: D

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.

2. The manic client has just interrupted the group session with the counselor for the 4th time, explaining that she already knows this information on 'dealing with others when you are down' and constantly gets up and goes to the front. What should the nurse do at this time?

Correct answer: A

Rationale: In this situation, it is important to redirect the client's energy and focus. Engaging the client in a purposeful activity like making another pot of coffee can help distract them from disruptive behavior and provide an outlet for their excess energy. This choice also helps in maintaining a therapeutic environment by involving the client in a constructive task. Asking the client to reflect on their behavior (Choice B) might not be effective during a manic episode as the client may not be in a state to critically analyze their actions. Asking the group to tell the client how they feel (Choice C) can escalate the situation and may not be appropriate in this context. Instructing the client to perform jumping jacks and count aloud (Choice D) may not address the underlying issue of disruptive behavior and may not be suitable for the current situation.

3. A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?

Correct answer: B

Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.

4. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

5. What type of diet is appropriate for a client with chronic cirrhosis?

Correct answer: A

Rationale: The correct diet for a client with chronic cirrhosis is high calorie, low protein. Cirrhosis can lead to impaired protein metabolism, making it essential to limit protein intake. High-calorie foods help meet the client's energy needs. Choice B (High protein, high calorie) is incorrect because high protein intake can worsen hepatic encephalopathy. Choice C (Low fat, low sodium) is not the most appropriate diet for cirrhosis as the focus should be on calories and protein. Choice D (High calorie, low sodium) does not address the need to restrict protein intake, which is crucial in cirrhosis.
