Nursing Elites

1. The client with chronic renal failure is receiving hemodialysis. Which of the following laboratory values should the nurse monitor closely?

• A. Hemoglobin level.
• B. Blood urea nitrogen (BUN) level.
• C. Serum potassium level.
• D. Creatinine level.

Correct answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

2. The patient will begin taking doxycycline to treat an infection. When should the nurse plan to give this medication?

• A. 1 hour before or 2 hours after a meal.
• B. with an antacid to minimize GI irritation.
• C. with food to improve absorption.
• D. with small sips of water.

Correct answer: C

Rationale: Doxycycline is a lipid-soluble tetracycline that is better absorbed when taken with milk products and food. Taking doxycycline with food helps improve its absorption. It should not be taken on an empty stomach, as this can decrease its effectiveness. Antacids can interfere with the absorption of tetracyclines, so they should not be taken together. While it is important to stay hydrated when taking medications, small sips of water are not specifically recommended for doxycycline administration.

3. How can a nurse best help a client undergoing a bone marrow aspiration and biopsy, along with two upset family members, manage anxiety during the procedure?

• A. Allow the client's family to stay for emotional support.
• B. Accompany the client silently.
• C. Encourage the client to take slow, deep breaths to promote relaxation.
• D. Provide the client an opportunity to verbalize emotions.

Correct answer: C

Rationale: Encouraging the client to take slow, deep breaths is an effective way for the nurse to help the client manage anxiety during the bone marrow aspiration and biopsy procedure. Slow, deep breathing can promote relaxation and help reduce anxiety levels. Choice A, allowing the client's family to stay for emotional support, may provide comfort but does not address a direct intervention to help manage anxiety. Choice B, staying with the client silently, may not actively help the client address their anxiety. Choice D, allowing the client to express feelings, is important but may not directly address anxiety management during the procedure.

4. When monitoring a client who is receiving tissue plasminogen activator (t-PA), the nurse should have resuscitation equipment available because reperfusion of the cardiac tissue can result in which of the following?

• A. Cardiac arrhythmias.
• B. Hypertension.
• C. Seizures.
• D. Hypothermia.

Correct answer: A

Rationale: The correct answer is A: Cardiac arrhythmias. Reperfusion of cardiac tissue following t-PA administration can lead to cardiac arrhythmias, necessitating resuscitation equipment. Hypertension (choice B) is a common side effect of t-PA but is not directly related to reperfusion. Seizures (choice C) and hypothermia (choice D) are not typically associated with reperfusion from t-PA administration.

5. What is the most common cause of peptic ulcers?

• A. Helicobacter pylori infection
• B. NSAID use
• C. Excessive alcohol consumption
• D. Stress

Correct answer: A

Rationale: Helicobacter pylori infection is the most common cause of peptic ulcers. This bacterium can weaken the protective mucous coating of the stomach and duodenum, allowing acid to get through to the sensitive lining beneath. NSAID use (Choice B) can also cause peptic ulcers by disrupting the stomach's mucosal barrier. Excessive alcohol consumption (Choice C) and stress (Choice D) can exacerbate and contribute to ulcer formation but are not the primary cause.
