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 of the following medications is not classified as a neuromuscular blocker?
- A. Anectine
- B. Pavulon
- C. Pitressin
- D. Mivacron
Correct answer: C
Rationale: The correct answer is Pitressin. Pitressin is a hormone replacement medication and is not classified as a neuromuscular blocker. Choices A, B, and D (Anectine, Pavulon, Mivacron) are neuromuscular blockers used during anesthesia to induce muscle relaxation for various procedures. Anectine is also known as succinylcholine, Pavulon is rocuronium, and Mivacron is mivacurium. These medications act on the neuromuscular junction to block the transmission of nerve impulses, leading to muscle relaxation.
3. A 46-year-old has returned from a heart catheterization and wants to get up to start walking 3 hours after the procedure. The nurse should:
- A. Tell the patient to remain with the leg straight for at least another hour and check the chart for activity orders.
- B. Allow the patient to begin limited ambulation with assistance.
- C. Recommend a physical therapy consultation for ambulation.
- D. Tell the patient to remain with the leg straight for another 6 hours and check the chart for activity orders.
Correct answer: A
Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events. Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications. Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff. Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.
4. What essential assessment must be performed for clients with implanted dialysis access devices?
- A. Color and capillary refill
- B. Patency and pulse
- C. Thrill and bruit
- D. Trousseau's and temperature
Correct answer: C
Rationale: Correct! When assessing clients with implanted dialysis access devices, it is crucial to palpate for the thrill, which indicates blood flow, and auscultate for the bruit, a humming sound, to ensure the patency of the access device. Choices A, B, and D are incorrect as they are not specific assessments related to dialysis access devices. Checking color and capillary refill, pulse, Trousseau's sign, and temperature are important assessments in other contexts but not specifically for monitoring implanted dialysis access devices.
5. A patient has been diagnosed with diabetes mellitus. Which of the following is not a clinical sign of diabetes mellitus?
- A. Polyphagia
- B. Polyuria
- C. Metabolic acidosis
- D. Lower extremity edema
Correct answer: D
Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.
