Nursing Elites

1. A client with chronic heart failure is being discharged with a new prescription for furosemide. Which instruction should the nurse include in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Restrict your fluid intake to 1 liter per day.
• C. Avoid salt substitutes containing potassium.
• D. Weigh yourself once a week.

Correct answer: A

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss due to increased urinary excretion. Potassium-rich foods can help prevent hypokalemia, a potential side effect of furosemide. Restricting fluid intake (choice B) may not be suitable for all patients with heart failure, and a general restriction of 1 liter per day is not typically recommended. Avoiding salt substitutes containing potassium (choice C) is not a priority teaching point in this scenario. Weighing oneself once a week (choice D) is important for monitoring fluid status, but increasing potassium-rich foods is more directly related to the potential side effects of furosemide.

2. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?

• A. Metabolic acidosis.
• B. Respiratory acidosis.
• C. Metabolic alkalosis.
• D. Respiratory alkalosis.

Correct answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

3. 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.

4. What could suddenly occur in a child with acute epiglottitis?

• A. Increased carbon dioxide levels
• B. Airway obstruction
• C. Inability to swallow
• D. Bronchial collapse

Correct answer: B

Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.

5. An infant has been diagnosed with cradle cap. What is the correct intervention to treat the scalp?

• A. Alcohol
• B. Mineral oil
• C. Calamine
• D. A&D ointment

Correct answer: B

Rationale: Cradle cap is a common condition in infants characterized by crusty patches on the scalp. The correct intervention to treat cradle cap is to apply mineral oil. Mineral oil helps soften the crusty patches, making it easier to remove them gently. Alcohol (Choice A) can be too harsh for an infant's sensitive skin and may cause irritation. Calamine (Choice C) is used to relieve itching associated with conditions like chickenpox or insect bites, not for treating cradle cap. A&D ointment (Choice D) is typically used for diaper rash and minor skin irritations, not for cradle cap.
