Nursing Process Final Exam Questions

Correct Answer: A

Rationale: The correct answer is A: Have the patient lie flat for 6 to 8 hours after a lumbar puncture to prevent complications like post-lumbar puncture headache. Lying flat helps maintain CSF pressure and reduce the risk of leakage. B: Keeping the patient from eating or drinking for 4 hours is not necessary after a lumbar puncture. C: Monitoring pedal pulses q4h is irrelevant to post-lumbar puncture care. D: Keeping the head of the bed elevated 30 degrees for 24 hours is not recommended after a lumbar puncture as it may increase the risk of complications.

Correct Answer: D

Rationale: The correct answer is D. Carbogen is a gas mixture of carbon dioxide and oxygen. Inhaling carbogen can stimulate respiration due to increased oxygen levels and carbon dioxide acting as a respiratory stimulant. It can also dilate blood vessels, enhancing oxygen delivery to tissues. Additionally, carbogen can help dislodge blood clots by improving blood flow and oxygenation. Therefore, all the choices (A, B, and C) are correct as inhaling carbogen can have multiple beneficial effects on respiration, blood vessels, and blood clot dislodging.

Correct Answer: B

Rationale: The correct answer is B: Creamy white patches. These patches are indicative of oral thrush, a common fungal infection seen in individuals with weakened immune systems like those with AIDS. This infection is caused by Candida albicans. It presents as white patches on the tongue, inner cheeks, or roof of the mouth. Halitosis (A) is bad breath, not specific to AIDS. Carious teeth (C) refers to cavities, not directly related to AIDS. Swollen lips (D) can be a symptom of various oral conditions, but not specific to AIDS. In summary, creamy white patches are a characteristic oral problem associated with AIDS due to opportunistic infections like oral thrush.

Correct Answer: B

Rationale: The correct answer is B: 7 to 14 days. Marrow suppression from floxuridine typically occurs 1-2 weeks after administration due to its effects on rapidly dividing cells in the bone marrow. This is known as the nadir period. Choices A, C, and D are incorrect because 24 hours is too soon for noticeable effects, 2 to 4 days is too short for the nadir period, and 21 to 28 days is too long for the onset of marrow suppression. The correct choice aligns with the expected timeframe for floxuridine's impact on bone marrow function.

Correct Answer: B

Rationale: The correct answer is B: Use a soft toothbrush and electric razor. Patients with bone marrow depression are at increased risk of bleeding due to low platelet count. Using a soft toothbrush and electric razor helps prevent injury to the gums and skin, reducing the risk of bleeding. Choices A, C, and D are incorrect because: A: Sleeping with the head of the bed slightly elevated is not directly related to preventing bleeding in bone marrow depression. C: Drinking citrus juices may irritate the stomach lining and are not specifically indicated for preventing bleeding. D: Increasing activity level and frequent ambulation may increase the risk of injury and bleeding in a patient with bone marrow depression.
