Correct Answer: B

Rationale: Irritability is an early sign that suctioning is necessary to clear the airway in a client with a tracheostomy. When secretions build up in the tracheostomy tube, the client may become irritable due to the discomfort and the compromised airway. Bradycardia, confusion, and hypotension are not typically early signs that suctioning is required. Bradycardia may occur if the airway becomes severely compromised, confusion may be a late sign of hypoxia, and hypotension is not directly related to the need for suctioning in a client with a tracheostomy.

Correct Answer: B

Rationale: The correct answer is B: Persistent cough. Enalapril is an ACE inhibitor that can cause a persistent cough as a common side effect. This symptom should be reported to the healthcare provider to evaluate if a medication adjustment is needed. Choices A, C, and D are not typically associated with enalapril use and are less likely to be directly related to the medication. Increased heart rate, constipation, and sweating are not commonly linked to enalapril, so they are not the priority findings to report in this case.

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.

Correct Answer: B

Rationale: The correct answer is to verify the client's blood type before administration. This step is crucial to ensure compatibility and prevent adverse reactions such as hemolytic transfusion reactions. Warming the blood to body temperature (Choice A) is not the first step and is not typically done during blood transfusions. Administering the blood through an IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow infusion. Administering diuretics before the transfusion (Choice D) is unnecessary and not a standard practice when initiating a blood transfusion.

Correct Answer: C

Rationale: The correct action to prevent dislocation of the prosthesis after hip replacement surgery is to avoid placing a pillow under the client's knees. Placing a pillow can cause hip adduction, leading to dislocation. Crossing the client's legs at the knees and elevating the client's legs can also increase the risk of hip dislocation. Maintaining the client's legs in a neutral position is important to prevent complications.
