Correct Answer: C

Rationale: Monitoring for signs of infection is critical, as prednisone, a corticosteroid, suppresses the immune system, increasing infection risk in clients with adrenal insufficiency.
Choice A is incorrect because prednisone should be taken with food to reduce gastrointestinal irritation, not on an empty stomach.
Choice B is incorrect because prednisone for adrenal insufficiency is typically a lifelong therapy, not limited to a few weeks.
Choice D is incorrect because reducing the dose without medical guidance can precipitate an adrenal crisis; dose adjustments must be supervised by the provider.

Correct Answer: A

Rationale: Persistent fatigue lasting more than 6 months is a diagnostic criterion for chronic fatigue syndrome, characterized by debilitating fatigue not relieved by rest.
Choice B is incorrect because joint swelling is not a feature of chronic fatigue syndrome; it is more associated with inflammatory conditions like rheumatoid arthritis.
Choice C is incorrect because a fever of 38.5°C is not typical unless an infection is present; low-grade fevers may occur but are not primary.
Choice D is incorrect because weight gain is not a hallmark feature; weight changes may occur secondary to inactivity or medication.

Correct Answer: A

Rationale: Documenting the client's condition every 15 minutes is a crucial part of using restraints. Regular documentation helps ensure the safety and well-being of the client, as it allows for continuous monitoring and timely intervention if necessary. Requesting a PRN (as needed) restraint prescription for clients who are aggressive is not a recommended practice. Restraints should only be used as a last resort and must be based on a thorough assessment of the client's condition, not solely on their behavior. Attaching the restraint to the bed's side rails is not recommended. This can increase the risk of injury to the client. Restraints should be attached to a part of the bed frame that moves with the client, such as the head or footboard. While it's important to regularly check and adjust restraints for comfort and safety, there's no specific guideline that restraints should be removed every 4 hours. The frequency of removal and repositioning will depend on the individual client's condition and needs.

Correct Answer: A

Rationale: Administering albuterol via nebulizer is the first action to take during an acute asthma attack, as it rapidly relaxes bronchial smooth muscles, relieving bronchospasm and improving airflow.
Choice B is incorrect because a supine position can worsen breathing; a semi-Fowler's or upright position is preferred to facilitate lung expansion.
Choice C is incorrect because obtaining a peak expiratory flow rate is useful for monitoring but is not the priority during an acute attack.
Choice D is incorrect because administering oxygen is secondary to bronchodilator therapy unless the client has severe hypoxia (e.g., oxygen saturation <90%).

Correct Answer: C

Rationale:
Choice A is wrong because maintaining a semi-Fowler's position during testing is not necessary. You can sit or stand up straight, but make sure you do it the same way each time.
Choice B is wrong because placing tongue on the mouthpiece of the meter can block the air flow and affect the accuracy of the measurement. You should close your lips tightly on the mouthpiece instead. This is because a peak flow meter measures how fast you can push air out of your lungs when you blow out as hard and as fast as you can. This is called peak expiratory flow rate (PEFR) or peak expiratory flow (PEF). It shows how open the airways are in the lungs and can help detect early signs of worsening asthma.
Choice D is wrong because recording the average of the readings is not recommended. You should record the highest of the three readings on a sheet of paper, calendar, or in your asthma diary. This is your daily peak flow.
