Correct Answer: A

Rationale: The correct answer is A: Crush medications and mix with food. When administering oral medications to a patient with dysphagia, crushing the medications and mixing them with food is a common method to aid in swallowing. Choice B is incorrect because using a straw could pose a choking hazard for patients with dysphagia. Choice C is incorrect as thickened liquids may not always be suitable for all medications. Choice D is incorrect because having the patient lie flat can increase the risk of aspiration, which is not recommended for patients with dysphagia.

Correct Answer: C

Rationale: Irritability is an early indicator that suctioning is needed for a client with a tracheostomy because it can signal discomfort or difficulty breathing due to mucus accumulation, prompting the need for suctioning to clear the airway. Bradycardia (Choice A) and hypotension (Choice B) are not typically early indicators of the need for suctioning in a client with a tracheostomy. Confusion (Choice D) is also not a direct early indicator of the need for suctioning in this context.

Correct Answer: B

Rationale: The correct recommendation for constipation is to increase dietary fiber to promote bowel movements. Dietary fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Administering a laxative (Choice A) is not the first-line recommendation and should be used cautiously due to potential side effects. Resting until symptoms resolve (Choice C) and encouraging bed rest (Choice D) are not effective interventions for relieving constipation.

Correct Answer: C

Rationale: When caring for a client diagnosed with delirium, the most important condition for the nurse to investigate is prescription drug intoxication. Delirium can be caused by various factors, and prescription drug intoxication is a common reversible cause. Investigating this factor first is crucial to identify and address the underlying cause promptly. Choices A, B, and D are less likely to be directly associated with delirium compared to prescription drug intoxication. While cancer, impaired hearing, and heart failure can have their complications and effects, they are not typically the primary causes of delirium in a client.

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.
