In a client who has human immunodeficiency virus (HIV) infection, CD4+ levels are measured to determine the:
- A. Presence of opportunistic infections
- B. Extent of immune system damage
- C. Level of the viral load
- D. Resistance to antigens
Correct Answer: B
Rationale: Step-by-step rationale:
1. CD4+ cells are a type of white blood cell crucial for immune function.
2. HIV targets and destroys CD4+ cells, leading to immune system damage.
3. Measuring CD4+ levels helps determine the extent of this damage.
4. Therefore, the correct answer is B.
Summary:
A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose.
C: Level of the viral load - Measured separately from CD4+ levels.
D: Resistance to antigens - CD4+ levels do not directly indicate resistance.

Deaths have occurred when potassium chloride has been used incorrectly to flush a lock or central venous catheter. Which of the ff precautions should a nurse take to minimize this risk?
- A. Use a dilute form of potassium chloride before flushing locks
- B. Warm the KCL before flushing locks
- C. Read labels carefully on vials containing flush solutions for locks
- D. Replace the existing locks with new ones to avoid flushing
Correct Answer: C
Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used.
Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly.
Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride.
Summary:
- Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration.
- Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride.
- Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.
The nurse inserts an intravenous (IV) catheter using the correct technique and following the recommended steps according to standards of care and hospital policy. Which type of implementation skill is the nurse using?
- A. Cognitive
- B. Interpersonal
- C. Psychomotor
- D. Judgmental
Correct Answer: C
Rationale: The correct answer is C: Psychomotor. The nurse is demonstrating psychomotor skills by inserting an IV catheter correctly. Psychomotor skills involve the ability to perform physical tasks effectively and efficiently. This skill requires coordination, dexterity, and precision. The other choices are incorrect because:
A: Cognitive skills involve thinking, analyzing, and problem-solving.
B: Interpersonal skills involve communication and interaction with others.
D: Judgmental skills involve critical thinking and decision-making.
A patient verbalizes a low pain level of 2 out of 10 but exhibits extreme facial grimacing while moving around in bed. What is the nurse’s initial action in response to these observations?
- A. Proceed to the next patient’s room to make rounds.
- B. Determine the patient does not want any pain medicine.
- C. Ask the patient about the facial grimacing with movement.
- D. Administer the pain medication ordered for moderate to severe pain.
Correct Answer: C
Rationale: The correct initial action for the nurse is to ask the patient about the facial grimacing with movement (Choice C). This is because the patient's non-verbal cues (facial grimacing) are contradicting their verbal report of low pain level. By asking the patient directly, the nurse can clarify the discrepancy and gain a better understanding of the patient's actual pain level and needs.
Choice A is incorrect as it disregards the patient's observed discomfort. Choice B assumes the patient does not want pain medicine without clarifying the situation first. Choice D is premature as administering pain medication without further assessment may not be appropriate or safe.
In summary, asking the patient about the facial grimacing is essential to ensure accurate pain assessment and appropriate intervention.
During preoperative teaching for a client who will undergo subtotal thyroidectomy, the nurse should include which statement?
- A. “The head of your bed must remain flat for 24 hours after surgery.”
- B. “You should avoid deep breathing and coughing after surgery.”
- C. “You won’t be able to swallow for the first day or two.”
- D. “You must avoid hyperextending your neck after surgery.”
Correct Answer: D
Rationale: The correct answer is D: “You must avoid hyperextending your neck after surgery.” This is because hyperextending the neck can put strain on the surgical incision site and increase the risk of complications. A: Incorrect, as the head of the bed should be elevated to reduce swelling and promote drainage. B: Incorrect, as deep breathing and coughing are important to prevent pneumonia and promote lung expansion. C: Incorrect, as swallowing may be difficult initially but should improve gradually.
A patient verbalizes a low pain level of 2 out of 10 but exhibits extreme facial grimacing while moving around in bed. What is the nurse’s initial action in response to these observations?
- A. Proceed to the next patient’s room to make rounds.
- B. Determine the patient does not want any pain medicine.
- C. Ask the patient about the facial grimacing with movement.
- D. Administer the pain medication ordered for moderate to severe pain.
Correct Answer: C
Rationale: The correct initial action is to choose C: Ask the patient about the facial grimacing with movement. This is important as the patient's non-verbal cues (facial grimacing) contradict their verbal pain report. By directly addressing the discrepancy, the nurse can gather more accurate information about the patient's pain experience and potentially identify any underlying issues causing the discrepancy.
Proceeding to the next patient's room (A) without addressing the discrepancy would neglect the patient's needs. Assuming the patient does not want pain medicine (B) based solely on the verbal report without further assessment is premature. Administering pain medication (D) without clarifying the situation may lead to inappropriate or ineffective treatment. Therefore, option C is the most appropriate initial action to ensure comprehensive and individualized patient care.
