Correct Answer: D

Rationale: TENS is a portable treatment that can be done at home, so the client should not expect to remain in the hospital for this treatment.

Correct Answer: A

Rationale: Assessing skin turgor by gently pinching the skin on the forearm is a reliable method to check for dehydration in elderly patients. When the skin is slow to return to its original position, it indicates dehydration. While assessing for dry mucous membranes is also important, checking skin turgor is a more direct method for dehydration assessment. Checking for orthostatic hypotension is more related to circulation status than dehydration. Measuring daily weights is helpful to monitor fluid balance but may not be as immediate or direct in detecting dehydration in elderly patients.

Correct Answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

Correct Answer: A

Rationale: The correct answer is A. Clinical manifestations of left-sided heart failure include pulmonary symptoms such as dyspnea, cough, and orthopnea. However, left-sided heart failure can also manifest as jugular venous distention and hepatojugular reflex due to the backflow of blood into the pulmonary circulation. Right-sided heart failure is characterized by systemic symptoms like hepatomegaly, ascites, and peripheral edema. Choice B is incorrect as it presents manifestations of right-sided heart failure. Choice C includes symptoms of left-sided heart failure. Choice D describes pulmonary congestion, which is more specific to left-sided heart failure, but it does not encompass the full range of clinical manifestations for left-sided heart failure.

Correct Answer: A

Rationale: The correct answer is A: Increased shortness of breath. In COPD, worsening symptoms often include increased shortness of breath due to impaired lung function. This indicates a decline in respiratory status and the need for prompt intervention. Choice B, decreased wheezing, is not indicative of worsening COPD as it could suggest better airflow. Choice C, productive cough with green sputum, may indicate an infection but not necessarily worsening COPD. Choice D, a slight increase in fatigue, is non-specific and may not directly correlate with the worsening of COPD.
