Nursing Elites

1. A nurse is admitting a client who has anorexia nervosa. Which of the following is an expected finding?

• A. Iron 90 mcg/dl.
• B. Prealbumin 10 mcg/dl.
• C. Serum creatinine 0.8 mg/dl.
• D. Calcium 9.5 mg/dl.

Correct answer: B

Rationale: Corrected Rationale: Low prealbumin levels are indicative of malnutrition, which is common in individuals with anorexia nervosa. Iron levels, serum creatinine, and calcium levels are not typically affected in the same way by anorexia nervosa, making choices A, C, and D incorrect.

2. A nurse is teaching a client who is at risk for developing osteoporosis. Which of the following recommendations should the nurse make?

• A. Walk for at least 30 minutes each day
• B. Avoid sunlight exposure
• C. Take vitamin B12 supplements
• D. Increase calcium intake to 1,500 mg per day

Correct answer: D

Rationale: The correct answer is to increase calcium intake to 1,500 mg per day. Adequate calcium intake is essential for maintaining bone density and reducing the risk of osteoporosis. Walking for at least 30 minutes each day is beneficial for overall health but is not as directly related to osteoporosis prevention as calcium intake. Sunlight exposure is important for vitamin D synthesis, which is necessary for calcium absorption, so avoiding sunlight exposure would not be recommended. Vitamin B12 supplements are not directly related to bone health or osteoporosis prevention, so this would not be the most appropriate recommendation.

3. A nurse is planning an educational program for high school students about cigarette smoking. Which of the following potential consequences of smoking is most likely to discourage adolescents from using tobacco?

• A. Use of tobacco might lead to alcohol and drug abuse.
• B. Smoking in adolescence increases the risk of developing lung cancer later in life.
• C. Use of tobacco decreases the level of athletic ability.
• D. Smoking in adolescence increases the risk of lifelong addiction.

Correct answer: C

Rationale: The most likely consequence to discourage adolescents from smoking is the immediate effect of decreased athletic ability. This consequence is more tangible and relevant to high school students compared to long-term health risks like lung cancer or addiction. While choices A, B, and D are all negative outcomes of smoking, choice C is more likely to have a direct impact on adolescents due to its immediate and visible effects on their physical performance.

4. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

5. Which of the following is an early sign that suctioning is required for a client with a tracheostomy?

• A. Bradycardia
• B. Irritability
• C. Confusion
• D. Hypotension

Correct answer: B

Rationale: Irritability is an early sign that suctioning is necessary to clear the airway in a client with a tracheostomy. When secretions build up in the tracheostomy tube, the client may become irritable due to the discomfort and the compromised airway. Bradycardia, confusion, and hypotension are not typically early signs that suctioning is required. Bradycardia may occur if the airway becomes severely compromised, confusion may be a late sign of hypoxia, and hypotension is not directly related to the need for suctioning in a client with a tracheostomy.
