Nursing Elites

1. The nurse uses a diagram to show that the tetralogy of Fallot involves a combination of four congenital defects. What are the defects?

• A. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy
• B. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
• C. Aortic stenosis, atrial septal defect, overriding aorta, right ventricular hypertrophy
• D. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy

Correct answer: B

Rationale: The correct answer is B: Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. Tetralogy of Fallot involves these four congenital defects. Choice A is incorrect because it includes aortic stenosis instead of pulmonary stenosis, atrial septal defect instead of ventricular septal defect, and left ventricular hypertrophy instead of right ventricular hypertrophy. Choice C is incorrect as it includes aortic stenosis and atrial septal defect instead of pulmonary stenosis and ventricular septal defect. Choice D is incorrect because it includes aortic hypertrophy instead of overriding aorta.

2. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?

• A. When the fever dissipates
• B. After the incubation period
• C. When the lesions have healed
• D. When the lesions are crusted over

Correct answer: D

Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.

3. A male client with Herpes Zoster (shingles) on his thorax tells the nurse that he is having difficulty sleeping. What is the etiology of this problem?

• A. Pain
• B. Nocturia
• C. Dyspnea
• D. Frequent cough

Correct answer: A

Rationale: The correct answer is A: Pain. The pain caused by Herpes Zoster (shingles) can disrupt sleep patterns. It is a common symptom of shingles and can lead to difficulty falling asleep or staying asleep. Nocturia (B), dyspnea (C), and frequent cough (D) are not typically associated with shingles and would not directly cause difficulty sleeping in this scenario.

4. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?

• A. Low oxygen levels are present in the blood.
• B. High levels of carbon dioxide have accumulated in the blood.
• C. Increased bicarbonate levels are causing alkalosis.
• D. Respiratory rate is increased, causing hyperventilation.

Correct answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

5. The nurse is providing postoperative care for a client who had a thyroidectomy. Which assessment finding requires immediate intervention?

• A. Hoarseness and weak voice
• B. Calcium level of 8.0 mg/dL (2.0 mmol/L)
• C. Heart rate of 110 beats per minute
• D. Difficulty swallowing

Correct answer: D

Rationale: Difficulty swallowing can indicate swelling or hematoma formation, which may compromise the airway and requires immediate intervention. Hoarseness and a weak voice are expected post-thyroidectomy due to manipulation of the laryngeal nerves but do not require immediate intervention. A calcium level of 8.0 mg/dL is within the normal range (8.5-10.5 mg/dL) and may not require immediate intervention. A heart rate of 110 beats per minute may be elevated due to stress or pain postoperatively, but it does not indicate an immediate threat to the airway.
