A nurse is reinforcing postoperative teaching with a client who has a prescription for enoxaparin to prevent deep vein thrombosis. Which of the following information should the nurse include in the teaching as a potential adverse effect of this medication?

A. Reviewing the results of the client's chlamydia screening with their parents, without the client's consent: Sexual health information, including STI screenings, is protected by confidentiality laws even for minors in many regions. Disclosing such sensitive information without the client's consent breaches confidentiality and can undermine trust between the adolescent and healthcare providers.

B. Reviewing the results of the client's celiac screening with their parents, without the client's consent: Celiac screening relates to general medical conditions and nutritional health, which are typically shared with parents of minors unless otherwise restricted. This does not generally breach confidentiality because it is not considered sensitive under adolescent health privacy laws.

C. Reviewing the results of the client's complete blood count (CBC) with their parents, without the client's consent: A CBC is a routine diagnostic test that checks general health indicators such as anemia or infection. Discussing these results with parents, especially for minors, is standard practice and does not usually violate confidentiality.

D. Reviewing the results of the client's urinalysis with their parents, without the client's consent: Urinalysis results typically assess general health or identify infections, which are standard to share with parents in the care of minors. This action would not be considered as a breach of confidentiality unless it revealed sensitive information like substance use without consent.

A. Anuria: Anuria, or the absence of urine output, indicates severe dehydration or acute renal failure rather than moderate dehydration. Moderate dehydration usually presents with decreased but not absent urine output, as the body still tries to conserve fluids.

B. A 7% weight loss from baseline: A weight loss of 6% to 9% of body weight is consistent with moderate dehydration in infants and children. This measurable sign is a critical and objective indicator used to assess the severity of dehydration, particularly following prolonged vomiting or diarrhea.

C. Hyperpnea: Hyperpnea, or abnormally deep and rapid breathing, can be seen in cases of severe dehydration or metabolic acidosis. It is not a classic finding of moderate dehydration, where respiratory patterns are usually normal or only mildly affected.

D. Lethargy: Lethargy typically suggests severe dehydration rather than moderate. In moderate dehydration, the infant may be irritable or thirsty but usually maintains normal mental status without profound decreases in responsiveness or alertness.
