Nursing Elites

1. Which laboratory value is most important to monitor for a patient receiving heparin therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.

2. When preparing to administer a medication through a nasogastric (NG) tube, what is the first action the nurse should take?

• A. Check the placement of the NG tube
• B. Flush the tube with saline
• C. Position the client in a semi-Fowler's position
• D. Administer the medication slowly

Correct answer: A

Rationale: The correct first action when preparing to administer a medication through a nasogastric (NG) tube is to check the placement of the NG tube. This step is essential to ensure that the tube is correctly positioned in the stomach and not in the lungs, preventing potential complications. Flushing the tube with saline may be required, but it should follow the verification of tube placement. Positioning the client in a semi-Fowler's position is necessary for comfort during the procedure but is not the initial step. Administering the medication can only be done safely after confirming the correct placement of the NG tube.

3. Which electrolyte imbalance is most likely to cause cardiac arrhythmias?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.

4. A client post-lobectomy is placed on mechanical ventilation. The nurse notices the client is fighting the ventilator. What should the nurse do first?

• A. Increase the sedation as prescribed.
• B. Manually ventilate the client using an ambu bag.
• C. Check the ventilator settings and alarms.
• D. Suction the client’s airway.

Correct answer: C

Rationale: The correct first action for the nurse to take when a client is fighting the ventilator is to check the ventilator settings and alarms. This step is crucial to ensure that the ventilator is functioning correctly and providing the necessary support to the client. Increasing sedation (Choice A) should only be considered after confirming that the ventilator settings are appropriate. While manually ventilating the client (Choice B) may be required in some cases, it is not the initial action to take. Suctioning the client's airway (Choice D) is not the priority in this situation, where the primary concern is addressing the client's struggle with the ventilator.

5. Rehabilitation after illness is classified under which level of healthcare?

• A. Primary
• B. Secondary
• C. Tertiary
• D. All three

Correct answer: C

Rationale: Rehabilitation after illness is classified as tertiary care. Tertiary care aims to help patients recover from illness, injuries, or disabilities, and restore their functionality. Primary care involves preventive measures and early disease detection, while secondary care focuses on diagnosis and treatment of specific conditions. Therefore, choices A, B, and D are incorrect as they do not specifically address the specialized nature of rehabilitation in healthcare.
