Correct Answer: B

Rationale: Weighing the client daily is a priority action when caring for a client with heart failure because it helps monitor fluid balance. This monitoring is essential in managing heart failure as it allows healthcare providers to assess for signs of fluid retention or depletion, which are crucial in adjusting treatment plans. Encouraging the client to drink fluids frequently (Choice A) may worsen fluid overload in heart failure patients. Increasing fluid intake (Choice C) can exacerbate fluid retention. While limiting sodium intake (Choice D) is important in heart failure management, monitoring fluid balance through daily weighing takes precedence as a priority nursing action.

Correct Answer: A

Rationale: The correct answer is A: Poor hygiene and dehydration are common risk factors for urinary tract infections (UTIs). While choices B, C, and D may play a role in certain cases, poor hygiene and dehydration are more universally recognized as key factors contributing to UTIs. Increased sexual activity and pregnancy (choice B) can also increase the risk of UTIs, but they are not as universal as poor hygiene and dehydration. Choices C and D, the use of urinary catheters and prolonged bed rest, and family history and obesity, respectively, are risk factors for UTIs but are not as commonly associated as poor hygiene and dehydration.

Correct Answer: B

Rationale: The correct answer is to wipe the drainage port after emptying. This action helps reduce the risk of infection by maintaining cleanliness. Positioning the drainage bag below the bladder (choice A) is incorrect as it should be positioned below the level of the bladder to prevent backflow of urine. Inserting the catheter using sterile technique (choice C) is not necessary for routine emptying of the drainage bag. Avoiding cleansing the urinary meatus (choice D) is incorrect as proper hygiene should be maintained to prevent infections.

Correct Answer: A

Rationale: The correct answer is A. Assessing the patient's age and mobility are key factors in determining fall risk. Age can affect balance and reaction time, while mobility influences the patient's stability. Choices B, C, and D are important considerations in assessing a patient's fall risk as well, but age and mobility play a more direct role in determining the patient's susceptibility to falls.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps maintain airway patency by preventing the collapse of small airways during exhalation, improving breathing efficiency. Administering oxygen at 2 L/min via nasal cannula may be appropriate for some COPD patients but is not the priority intervention. Positioning the client in high Fowler's position may help improve breathing but is not as specific as pursed-lip breathing for COPD. Encouraging deep breathing and coughing may be beneficial in other respiratory conditions, but it is not the most effective intervention for COPD.
