Correct Answer: D

Rationale: The correct answer is D because metformin should be held before a contrast CT scan to prevent the risk of kidney damage. Choices A, B, and C are all correct statements regarding the preparation and experience of a CT scan with contrast. It is important to fast before the procedure, keep the head still during the scan, and expect a warm sensation when the dye is injected.

Correct Answer: D

Rationale: The correct answer is D. Emailing client information through an unencrypted server is a HIPAA violation because it can lead to data breaches. Choices A, B, and C do not violate HIPAA. Posting the name of the nurse providing care on a client's communication board does not disclose sensitive health information. Discussing the client's new medication with a hospital pharmacist is a routine healthcare practice. Faxing requested medical information for a client who is transferring to another facility is a secure way to transmit healthcare data.

Correct Answer: B

Rationale: Evaluating electrolytes is crucial when addressing fluid overload as it helps determine the severity of the imbalance and guides treatment. Assessing for edema (Choice A) is important but not the priority over evaluating electrolytes. Restricting fluid intake (Choice C) and administering diuretics (Choice D) are interventions that may be necessary but should be based on the electrolyte evaluation to ensure safe and effective care.

Correct Answer: B

Rationale: During a client's transition into a new role, the presence of suicidal or homicidal ideation should be assessed due to the increased risk associated with significant life changes. This finding could indicate a need for immediate intervention. While assessing the client's ability to express feelings of guilt is important, it may not be the most critical aspect during this specific assessment. Changes in coping skills over time are relevant but might not be the primary focus during a role transition assessment. The client's involvement in community activities, although beneficial for social support, is not directly related to the immediate concerns of assessing a client transitioning into a new role.

Correct Answer: B

Rationale: The correct answer is to inject the medication at a 90-degree angle when administering an IM injection into the deltoid muscle. This angle ensures proper delivery of the medication into the muscle tissue. Choice A is incorrect because the gauge of the needle for a deltoid IM injection is usually smaller, around 23-25 gauge. Choices C and D are incorrect as the injection site for the deltoid muscle is approximately 2.54 cm (1 in) below the acromion process, not 12.7 cm (5 in).
