NCLEX PN Exam Cram
1. What is one characteristic of human immunodeficiency virus (HIV)?
- A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
- B. HIV replication occurs intracellularly.
- C. HIV integrates its genetic material into the host cell's DNA.
- D. DNA replication is irrelevant to HIV.
Correct answer: C
Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.
2. Which client should be seen first by the Emergency Department nurse?
- A. A six-year-old with a femur fracture.
- B. A two-year-old with a fever of 102 degrees F.
- C. A three-year-old with wheezes in the right lower lobe.
- D. A two-year-old whose gastrostomy tube came out.
Correct answer: A three-year-old with wheezes in the right lower lobe.
Rationale: The priority in the emergency department is to assess and manage clients based on the severity of their condition. In this scenario, the three-year-old with wheezes in the right lower lobe should be seen first because respiratory distress takes precedence over other conditions. Wheezing indicates potential airway compromise, which requires immediate attention to ensure adequate oxygenation. The other options are important but do not pose an immediate threat to the client's airway and breathing. A femur fracture, fever, or a dislodged gastrostomy tube can be addressed after ensuring the child with respiratory distress is stable.
3. The client is scheduled for surgical repair of a detached retina. What is the most likely preoperative nursing diagnosis for this client?
- A. Anxiety related to loss of vision and potential failure to regain vision.
- B. Deficient knowledge (preoperative and postoperative activities) related to lack of information.
- C. Acute pain related to tissue injury and decreased circulation to the eye.
- D. Risk for infection related to the eye injury.
Correct answer: Anxiety related to loss of vision and potential failure to regain vision.
Rationale: The correct preoperative nursing diagnosis for a client scheduled for surgical repair of a detached retina is 'Anxiety related to loss of vision and potential failure to regain vision.' A client facing the threat of permanent blindness due to a detached retina is likely to experience anxiety. Addressing this anxiety is crucial before providing education, as severe anxiety can hinder the client's ability to absorb new information. The nurse should offer emotional support, encourage the client to express concerns, and clarify any misconceptions. Acute pain is not a typical symptom of a detached retina, and the risk of infection preoperatively is minimal, making choices C and D less relevant in this scenario.
4. Which intervention should the nurse stop the nursing assistant from performing?
- A. Emptying the Jackson-Pratt drainage of the client post cholecystectomy
- B. Performing passive range of motion on the client with right-sided paralysis
- C. Placing the traction weights on the bed to transfer the client to X-ray
- D. Discarding the first urine voided by the client starting a 24-hour urine test
Correct answer: Placing the traction weights on the bed to transfer the client to X-ray
Rationale: Placing traction weights on the bed to transfer the client to X-ray is an intervention that the nurse should stop the nursing assistant from performing. Traction should never be relieved without a doctor's order as it can result in muscle spasm and tissue damage. The other choices are appropriate nursing interventions and should not be stopped. Emptying the Jackson-Pratt drainage, performing passive range of motion, and collecting the first urine void for a 24-hour urine test are all within the scope of practice and do not pose immediate risks to the client's well-being.
5. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: ondansetron (Zofran)
Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.
