A client with Alzheimer's disease is exhibiting signs of agitation and aggression. What is the nurse's priority intervention?

A. Reassure the client and provide emotional support.

B. Redirect the client to a quiet activity.

C. Administer a PRN dose of lorazepam.

D. Apply soft restraints as needed to prevent harm.

Correct Answer: B
Rationale: The correct answer is to redirect the client to a quiet activity. This intervention helps reduce agitation and aggression in clients with Alzheimer's disease by providing a distraction and promoting a calming environment. Reassuring the client and providing emotional support (Choice A) can be beneficial but is not the priority in this situation. Administering a PRN dose of lorazepam (Choice C) should not be the first intervention due to the risk of adverse effects and should only be considered if other non-pharmacological interventions are ineffective. Applying restraints (Choice D) should be avoided unless absolutely necessary for the client's safety as it can lead to further distress and is not the initial priority intervention.

A client in labor is experiencing late decelerations in fetal heart rate. What intervention should the nurse perform first?

• A. Reposition the client onto her left side.
• B. Apply oxygen via nasal cannula.
• C. Prepare for an emergency cesarean section.
• D. Increase IV fluid administration to improve perfusion.

Correct Answer: A
Rationale: Late decelerations indicate fetal distress due to compromised placental perfusion. Repositioning the client onto her left side is the priority intervention as it can increase blood flow to the placenta, improving fetal oxygenation. Applying oxygen via nasal cannula (choice B) can be the next step after repositioning if late decelerations persist. Emergency cesarean section (choice C) is not the initial action for late decelerations unless other interventions are ineffective. Increasing IV fluid administration (choice D) is not the first-line intervention for late decelerations; repositioning takes precedence to address the underlying cause.

A client with diabetes mellitus is admitted with an infected foot ulcer. What intervention is most important for the nurse to implement?

• A. Obtain a wound culture for testing.
• B. Administer prescribed IV antibiotics.
• C. Elevate the affected foot to reduce swelling.
• D. Consult the wound care nurse for assessment.

Correct Answer: B
Rationale: Administering prescribed IV antibiotics is the most crucial intervention in managing an infected foot ulcer in a client with diabetes mellitus. Antibiotics help combat the infection and prevent its spread systemically, which is vital in diabetic clients to prevent serious complications like sepsis. While obtaining a wound culture (Choice A) may provide valuable information for targeted antibiotic therapy, administering antibiotics promptly takes precedence to prevent the infection from worsening. Elevating the affected foot (Choice C) can help reduce swelling but is not as urgent as administering antibiotics. Consulting the wound care nurse (Choice D) may be beneficial for long-term wound management but does not address the immediate need to control the infection.

A client with chronic obstructive pulmonary disease (COPD) is experiencing increased shortness of breath and fatigue. What is the nurse's first action?

• A. Administer a bronchodilator as prescribed.
• B. Check the client's oxygen saturation.
• C. Reposition the client to a high Fowler's position.
• D. Administer oxygen via nasal cannula.

Correct Answer: B
Rationale: The correct first action for a client with COPD experiencing increased shortness of breath and fatigue is to check the client's oxygen saturation. This assessment helps the nurse evaluate the client's respiratory status promptly. Administering a bronchodilator (Choice A) may be necessary but should come after assessing the oxygen saturation. Repositioning the client to a high Fowler's position (Choice C) can help improve breathing but should not precede oxygen saturation assessment. Administering oxygen via nasal cannula (Choice D) may be needed based on the oxygen saturation results, but assessing it first is crucial.

A client in heart failure (HF) presents with weakness and poor urine output. Which assessment finding requires immediate action?

• A. Heart rate of 122 bpm and respiratory rate of 28.
• B. Yellow sputum expectorated.
• C. Temperature of 100.5°F (38.1°C).
• D. Shortness of breath on exertion.

Correct Answer: C
Rationale: An elevated temperature may indicate infection and should be treated immediately in a client with heart failure.
