Correct Answer: A

Rationale: Placing the wheelchair at a 45-degree angle to the bed is the correct technique for transferring a client who is unable to walk from bed to a wheelchair. This positioning facilitates a safer and easier transfer by providing more space for maneuvering and reducing the distance the client needs to be moved. Positioning the wheelchair parallel to the bed (Choice B) may make the transfer more challenging due to limited space and a longer distance to move the client. Placing the wheelchair in front of the bed (Choice C) may not provide an optimal angle for the transfer. Having the client stand and pivot into the wheelchair (Choice D) is not appropriate for a client who is unable to walk and could increase the risk of falls or injuries during the transfer.

Correct Answer: B

Rationale: As individuals age, it is common to experience changes in vision and hearing, leading to some decline in these senses. Slower light touch sensation and slower fine finger movement are also typical findings associated with aging. However, some short-term memory decline is more closely related to cognitive aging rather than typical age-related changes in the neurologic system. Therefore, the correct answer is the decline in vision and hearing. Decreased risk of depression is not a typical finding in aging; in fact, the risk of depression may increase as individuals age.

Correct Answer: D

Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.

Correct Answer: D

Rationale: Nonverbal interventions are primarily used during the acceptance stage according to K¼bler-Ross's theory of death and dying. During the acceptance stage, the individual is more likely to be reflective and less communicative, making nonverbal interventions more effective. Choices A, B, and C are incorrect because anger, denial, and bargaining are stages that precede the acceptance stage in K¼bler-Ross's model, where verbal communication and processing emotions play a more significant role.

Correct Answer: A

Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.
