Nursing Elites

1. The nurse is caring for a client with a nasogastric tube to continuous suction. Which electrolyte imbalance should the nurse monitor for?

• A. Hypercalcemia.
• B. Hypokalemia.
• C. Hyponatremia.
• D. Hypomagnesemia.

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. When a client has a nasogastric tube to continuous suction, potassium loss through gastric fluids can lead to hypokalemia. Hypercalcemia (Choice A) is not typically associated with continuous suction. Hyponatremia (Choice C) involves sodium imbalance and is not directly related to nasogastric suction. Hypomagnesemia (Choice D) is not the primary concern in this situation, as potassium loss is more significant with gastric suction.

2. During a follow-up home visit, the nurse observes that a client with chronic obstructive pulmonary disease (COPD) is using accessory muscles to breathe and has a pulse oximetry reading of 88%. What action should the nurse take first?

• A. Administer a prescribed bronchodilator
• B. Increase the oxygen flow rate
• C. Instruct the client to perform pursed-lip breathing
• D. Notify the healthcare provider immediately

Correct answer: C

Rationale: In this situation, the nurse should first instruct the client to perform pursed-lip breathing. Pursed-lip breathing helps improve oxygenation and decrease the work of breathing in clients with COPD. Administering a bronchodilator or increasing the oxygen flow rate may be necessary interventions but addressing the breathing technique through pursed-lip breathing is the initial action to optimize oxygenation. Notifying the healthcare provider immediately is not the first action indicated in this scenario; the nurse should intervene promptly to assist the client in improving breathing before escalating the situation.

3. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

4. The healthcare provider is preparing to administer an intravenous antibiotic to a client with a central venous catheter. Which action is most important?

• A. Flush the catheter with heparin.
• B. Change the dressing at the insertion site.
• C. Check for blood return before administering the antibiotic.
• D. Use sterile technique when accessing the catheter.

Correct answer: D

Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.

5. A client presents at a community-based clinic with complaints of shortness of breath, headache, often uses a gasoline-powered pressure washer to clean equipment and farm buildings. Which type of poisoning is the most likely etiology of this client's symptoms?

• A. asbestos
• B. silica dust
• C. histoplasmosis
• D. carbon monoxide

Correct answer: D

Rationale: The correct answer is D, carbon monoxide poisoning. This client's symptoms of shortness of breath and headache are consistent with carbon monoxide exposure, which can result from using gasoline-powered equipment in poorly ventilated areas. Asbestos (choice A) is linked to respiratory issues but does not typically present with these acute symptoms. Silica dust (choice B) exposure is associated with lung damage, not the symptoms described. Histoplasmosis (choice C) is a fungal infection and would not typically manifest with the symptoms presented by the client.
