Nursing Elites

1. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?

• A. Calcium and magnesium
• B. Sodium and calcium
• C. Potassium and chloride
• D. Potassium and magnesium

Correct answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.

2. The nurse empties the nasogastric suction collection canister of a client who had a bowel resection the previous day and notes that 1000 ml of gastric secretions were collected in the last 4 hours. What condition is the client at risk for developing?

• A. Metabolic alkalosis
• B. Hyperkalemia
• C. Metabolic acidosis
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Metabolic alkalosis. Loss of gastric secretions, which contain stomach acid, can lead to metabolic alkalosis. Excessive loss of acid results in an increase in the blood pH, leading to alkalosis. Hyperkalemia (B) is an elevated potassium level and is not directly related to the loss of gastric secretions. Metabolic acidosis (C) is an acid-base imbalance characterized by low pH and bicarbonate levels, which is the opposite of what would occur with the loss of gastric secretions. Hypoglycemia (D) is low blood sugar and is not typically associated with the scenario described in the question.

3. A client arrived to the medical-surgical unit 4 hours after a transurethral resection of the prostate (TURP). A triple-lumen catheter for continuous bladder irrigation with normal saline is infusing, and the nurse observes dark, pink-tinged outflow with blood clots in the tubing and collection bag. Which action should the nurse take?

• A. Monitoring catheter drainage
• B. Decreasing the flow rate
• C. Irrigating the catheter manually
• D. Discontinuing infusing the solution

Correct answer: C

Rationale: In this scenario, the nurse should choose option C - irrigating the catheter manually. This action can help clear the clots from the catheter and ensure proper bladder drainage. Monitoring catheter drainage (option A) alone may not address the issue of clots obstructing the flow. Decreasing the flow rate (option B) could potentially worsen clot formation. Discontinuing the infusing solution (option D) without addressing the clots first may lead to inadequate irrigation and increase the risk of complications.

4. In a patient with anemia, which of the following is the primary symptom to assess?

• A. Fever.
• B. Chest pain.
• C. Shortness of breath.
• D. Muscle cramps.

Correct answer: C

Rationale: The correct answer is C: Shortness of breath. In a patient with anemia, the primary symptom to assess is shortness of breath. Anemia leads to a reduced oxygen-carrying capacity of the blood, resulting in tissues not receiving adequate oxygen. This can manifest as shortness of breath, especially during physical exertion. Fever (Choice A), chest pain (Choice B), and muscle cramps (Choice D) are not typically primary symptoms of anemia. Fever may suggest an infection, chest pain can be indicative of cardiac issues, and muscle cramps may be related to electrolyte imbalances or neuromuscular disorders.

5. A healthcare professional is reading the chest x-ray report of a client who has just been intubated. The report states that the tip of the endotracheal tube lies 1 cm above the carina. The healthcare professional interprets that the tube is positioned above:

• A. The first tracheal cartilaginous ring
• B. The point where the larynx connects to the trachea
• C. The bifurcation of the right and left main stem bronchi
• D. The area connecting the oropharynx to the laryngopharynx

Correct answer: C

Rationale: The carina is a cartilaginous ridge that separates the openings of the two main stem (right and left) bronchi. If an endotracheal tube is inserted past the carina, the tube will enter the right main stem bronchus due to the natural curvature of the airway. This positioning is dangerous as only the right lung will be ventilated. It can be identified as only the right lung will have breath sounds and rise and fall with ventilation. Choices A, B, and D are incorrect as they do not relate to the specific anatomical landmark mentioned in the scenario.
