1. Which of the following is an example of a tertiary prevention strategy?
- A. Administering childhood vaccinations
- B. Chemotherapy for cancer treatment
- C. Routine screening for hypertension
- D. Physical therapy for stroke rehabilitation
Correct answer: D
Rationale: The correct answer is D: Physical therapy for stroke rehabilitation. Tertiary prevention aims to prevent complications and manage existing conditions to improve the quality of life. Administering childhood vaccinations (A) is an example of primary prevention to prevent the onset of diseases. Chemotherapy for cancer treatment (B) is a form of secondary prevention focusing on early detection and treatment to stop the progression of the disease. Routine screening for hypertension (C) is also a form of secondary prevention to detect and treat hypertension early, preventing further complications.
2. Why are neonates predisposed to problems with thermoregulation?
- A. Renal function is not fully developed.
- B. Flexed posture favors heat loss.
- C. A large body surface area favors heat loss to the environment.
- D. A thick layer of subcutaneous fat provides excellent insulation.
Correct answer: C
Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.
3. Each statement is true of rickets, except one. Which is the exception?
- A. Rickets is being diagnosed more frequently in the United States.
- B. Rickets is caused by vitamin C deficiency.
- C. Tachetic deformities such as bow legs or knock-knees develop.
- D. A narrow and distorted chest occurs.
Correct answer: B
Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.
4. What are the key nursing interventions for a patient experiencing acute respiratory distress syndrome (ARDS)?
- A. Positioning the patient in a prone position
- B. Monitoring vital signs and lung sounds
- C. Preparing for mechanical ventilation
- D. Administering supplemental oxygen
Correct answer: A
Rationale: The correct answer is A: Positioning the patient in a prone position. Prone positioning is a key nursing intervention for patients with acute respiratory distress syndrome (ARDS) as it helps improve oxygenation by allowing better lung ventilation. Choice B, monitoring vital signs and lung sounds, is important but not a key intervention specific to ARDS. Choice C, preparing for mechanical ventilation, may be necessary in severe cases of ARDS but is not a primary nursing intervention. Choice D, administering supplemental oxygen, is a common supportive measure but is not specific to ARDS interventions.
5. What precaution should be advised to a patient following a cataract surgery?
- A. Wear dark glasses while outdoors
- B. Avoid NSAIDs
- C. Use warm compresses
- D. Apply cold packs
Correct answer: A
Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.
