What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct Answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

The nurse is caring for a client with an intravenous infusion of normal saline. The client reports pain and swelling at the IV site. What is the nurse's priority action?
- A. Slow the rate of infusion
- B. Apply a warm compress to the site
- C. Discontinue the IV infusion
- D. Elevate the affected arm
Correct Answer: C
Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.
A client is admitted with a diagnosis of congestive heart failure (CHF). Which intervention is most important to include in the plan of care?
- A. Restrict fluid intake
- B. Provide a high-sodium diet
- C. Encourage vigorous exercise
- D. Administer bronchodilators as prescribed
Correct Answer: A
Rationale: The correct answer is A: Restrict fluid intake. Fluid restriction is crucial in the management of congestive heart failure (CHF) as it helps prevent fluid overload, which can exacerbate CHF symptoms. Choices B, C, and D are incorrect. Providing a high-sodium diet would worsen fluid retention and increase the workload of the heart. Encouraging vigorous exercise can strain the heart further in CHF patients. Administering bronchodilators is not the priority intervention for CHF.
The nurse is caring for a client with a diagnosis of major depressive disorder who has been prescribed a selective serotonin reuptake inhibitor (SSRI). What is the most important teaching point?
- A. Take the medication with food.
- B. Expect to see improvement within 24 hours.
- C. Avoid drinking grapefruit juice.
- D. Report any thoughts of self-harm immediately.
Correct Answer: D
Rationale: The correct answer is D: 'Report any thoughts of self-harm immediately.' Clients prescribed SSRIs should be educated to report any thoughts of self-harm promptly, as these medications can initially increase suicidal ideation. Choice A is incorrect because SSRIs are usually taken on an empty stomach. Choice B is incorrect as it takes several weeks for SSRIs to reach their full effectiveness. Choice C is irrelevant to SSRI therapy.
A client with a history of seizure disorder who is receiving phenytoin (Dilantin) is being discharged. Which instruction should the nurse provide?
- A. Take the medication at bedtime.
- B. Monitor drug levels regularly.
- C. Avoid alcohol while taking this medication.
- D. Take the medication at the same time every day.
Correct Answer: B
Rationale: The correct answer is to instruct the client to monitor drug levels regularly. This is crucial for phenytoin (Dilantin) to ensure that the medication levels are within the therapeutic range and to prevent toxicity. Choice A, taking the medication at bedtime, is not specifically required for phenytoin administration. Choice C, avoiding alcohol, is generally a good practice with medications but is not as critical as monitoring drug levels for phenytoin. Choice D, taking the medication at the same time every day, is important for consistency but does not address the specific monitoring needs of phenytoin.
What is the most important information for the nurse to provide to a client with a diagnosis of major depressive disorder who is started on a selective serotonin reuptake inhibitor (SSRI)?
- A. Take the medication with food
- B. Avoid foods high in tyramine
- C. Report any thoughts of self-harm immediately
- D. Expect to see improvement within 24 hours
Correct Answer: C
Rationale: The correct answer is C: 'Report any thoughts of self-harm immediately.' When starting an SSRI, clients should be informed to report any thoughts of self-harm promptly. SSRIs can initially increase suicidal ideation, especially in the early stages of treatment. This information is crucial for the client's safety and well-being. Choices A, B, and D are incorrect because taking the medication with food, avoiding foods high in tyramine, and expecting immediate improvement within 24 hours are not the most critical pieces of information for a client starting on an SSRI.
