Nursing Elites

1. During CPR, when attempting to ventilate a client's lungs, the nurse notes that the chest is not moving. What action should the nurse take first?

• A. Use a laryngoscope to check for a foreign body lodged in the airway.
• B. Reposition the head to ensure that the airway is properly opened.
• C. Turn the client to the side and administer three back blows.
• D. Perform a finger sweep of the mouth to clear any obstructions.

Correct answer: B

Rationale: The most common reason for inadequate lung aeration during CPR is the incorrect positioning of the head, leading to airway obstruction. Therefore, the initial action should be to reposition the head to open the airway properly and attempt to ventilate again. Using a laryngoscope to check for foreign bodies in the airway (Choice A) is not the first step and could delay crucial interventions. Turning the client to the side and administering back blows (Choice C) is not indicated in this scenario as the focus is on ventilating the lungs. Performing a finger sweep of the mouth (Choice D) is not recommended as it may push obstructions further into the airway during CPR.

2. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.

3. 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.

4. After pericardiocentesis for cardiac tamponade, for which signs should the nurse assess the client to determine if tamponade is recurring?

• A. Decreasing pulse
• B. Rising blood pressure
• C. Distant muffled heart sounds
• D. Falling central venous pressure (CVP)

Correct answer: C

Rationale: After pericardiocentesis for cardiac tamponade, the nurse should assess for distant muffled heart sounds that were noted before the procedure. If these sounds return, it could indicate recurring pericardial effusion and potential tamponade. Therefore, the correct answer is the return of distant muffled heart sounds (Option C). Decreasing pulse (Option A) and falling central venous pressure (Option D) are not specific signs of recurring tamponade. Rising blood pressure (Option B) is also not a typical sign of tamponade recurrence; in fact, hypotension is more commonly associated with tamponade.

5. A client is hospitalized with heart failure (HF). Which intervention should the nurse implement to improve ventilation and reduce venous return?

• A. Perform passive range of motion exercises
• B. Place the client in high Fowler's position
• C. Administer oxygen via nasal cannula
• D. Increase the client's activity level

Correct answer: B

Rationale: In clients with heart failure, placing them in high Fowler's position is beneficial as it helps reduce venous return and improve ventilation. This position aids in decreasing the workload on the heart by promoting better lung expansion and oxygenation. Passive range of motion exercises (Choice A) are not directly related to improving ventilation or reducing venous return. Administering oxygen via nasal cannula (Choice C) may help with oxygenation but does not directly address reducing venous return. Increasing the client's activity level (Choice D) may worsen heart failure symptoms by increasing the workload on the heart.
