A nurse is preparing to administer medication to a preschooler and must convert the child's weight from pounds to kilograms. The child weighs 30 lb. How many kilograms does the child weigh?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is choice C: A physical therapist who is involved in the client's care.

Choice A rationale:

Disclosing health information to an insurance agency offering a life insurance policy typically requires the client's written permission due to the sensitive nature of the information being shared, including medical history and conditions.

Choice B rationale:

Revealing a client's diagnosis to a family member without written consent would violate the client's privacy rights. Health information is protected by privacy laws, and disclosure should only occur with the client's explicit permission.

Choice C rationale:

This is the correct entity to whom health information can be disclosed without the client's written permission. Health professionals who are actively involved in the client's care, such as a physical therapist, are considered part of the healthcare team and may need access to relevant health information for proper treatment.

Choice D rationale:

Disclosing health information to an employer completing a pre-employment screening generally requires the client's consent, as pre-employment screenings often involve sharing medical information that could impact the employment decision.

The correct answer is choice B: A thready pulse.

Choice A rationale:

BUN (blood urea nitrogen) level of 18 mg/dL falls within the normal range, which is typically around 7-20 mg/dL. An elevated BUN might indicate dehydration or kidney dysfunction, but a value of 18 mg/dL does not necessarily suggest fluid volume deficit.

Choice B rationale:

A thready pulse is a weak and easily compressible pulse that indicates poor circulation and reduced fluid volume in the circulatory system. Vomiting and diarrhea lead to fluid loss, which can result in fluid volume deficit. Thus, a thready pulse is a significant finding in this context.

Choice C rationale:

Hemoglobin level of 15 g/dL is within the normal range for hemoglobin (usually around 12-16 g/dL for women and 14-18 g/dL for men). While vomiting and diarrhea can lead to mild dehydration, a hemoglobin level of 15 g/dL alone does not strongly suggest fluid volume deficit.

Choice D rationale:

Prominent neck veins are typically associated with increased central venous pressure, which can indicate fluid volume overload rather than fluid volume deficit. In the context of vomiting and diarrhea, neck veins are unlikely to become prominent due to volume depletion.
