When teaching a client with left-leg weakness how to use a cane, which instruction should the nurse include?

Correct Answer: C

Rationale: The correct instruction for the client with left-leg weakness using a cane is to maintain two points of support on the floor. This ensures stability and balance while walking. Choice A is incorrect because the cane should be used on the strong side of the body to provide additional support. Choice B is incorrect as the cane and the weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.

Correct Answer: B

Rationale: The first nursing action when caring for a client with a wound infection is to perform a wound culture before applying antibiotics. This step is crucial to identify the specific infecting organism and determine the most effective antibiotic therapy. Choices A, C, and D are incorrect because changing the dressing, cleansing the wound, or applying a wet-to-dry dressing should only be done after obtaining the culture results and starting appropriate antibiotic treatment.

Correct Answer: C

Rationale: Upon noticing phlebitis at the IV site, the nurse should remove the IV catheter and restart it in another location. Phlebitis is inflammation of the vein, and leaving the IV catheter in place can lead to further complications such as infection. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider immediately (Choice B) is important, but the immediate action to prevent complications is to remove the IV catheter. Monitoring the site for signs of infection (Choice D) is necessary, but the priority action is to remove and reinsert the IV catheter to prevent worsening of the phlebitis.

Correct Answer: C

Rationale: Increasing fiber intake is the most appropriate nursing intervention for a client experiencing constipation. Fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Encouraging the client to remain in bed may exacerbate constipation by reducing movement and promoting inactivity. While stool softeners can be beneficial, they are typically used as a short-term solution and may not address the underlying issue of low fiber intake. Regular exercise is important for overall bowel health; however, in the immediate management of constipation, increasing fiber intake is the most effective intervention.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy. When a client with a tracheostomy is experiencing respiratory distress, the priority intervention is to clear the airway by suctioning the tracheostomy to remove secretions that may be obstructing the air passage. Administering a bronchodilator (Choice A) may be considered if bronchospasm is present, but the immediate focus should be on clearing the airway. Notifying the physician (Choice C) is important but should not delay the immediate intervention of suctioning. Increasing the oxygen flow rate (Choice D) may provide temporary relief, but addressing the root cause of the distress by suctioning is the priority.

Correct Answer: C

Rationale: The correct answer is C: 'Furrows in the tongue.' Dehydration commonly presents with furrows in the tongue due to decreased oral moisture. This physical finding indicates dehydration as the tongue loses moisture and becomes dry. Choice A, 'Bradycardia,' is not typically associated with dehydration; instead, tachycardia may be present as a compensatory mechanism. Elevated blood pressure, as mentioned in choice B, is not a typical finding in dehydration; in fact, dehydration often leads to a decrease in blood pressure. Polyuria, as in choice D, is more commonly associated with conditions like diabetes mellitus or diabetes insipidus, rather than dehydration.

Correct Answer: C

Rationale: Ataxia and incoordination are signs of phenytoin toxicity rather than adverse reactions to rifampin or isoniazid. These symptoms indicate that the client is experiencing an adverse effect of phenytoin, requiring a dose adjustment. Choice A is incorrect because rifampin is not typically associated with ataxia and incoordination. Choice B is incorrect as the development of ataxia and incoordination does not necessarily mean the seizure disorder is no longer under control. Choice D is incorrect as the symptoms are more indicative of phenytoin toxicity rather than adverse effects of combination antimicrobial therapy.

Correct Answer: B

Rationale: The most appropriate intervention for a client with phlebitis at the IV site is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and continuing the IV can lead to complications such as infection or thrombosis. Applying a warm compress may provide symptomatic relief but does not address the root cause. Increasing the IV flow rate is not indicated and may worsen the inflammation. Monitoring for signs of infection is important, but the priority is to remove the source of inflammation by discontinuing the IV.

Correct Answer: C

Rationale: The correct answer is C because avoiding solid foods after bariatric surgery is crucial to prevent complications and promote healing. Choice A is incorrect as carbonated beverages can cause discomfort and should be avoided. Choice B is incorrect as large meals are not suitable after bariatric surgery. Choice D is incorrect as taking small sips of liquids is encouraged to prevent dehydration and promote recovery.
