A nurse is providing teaching for a client who has binge-eating disorder and is morbidly obese. The client has been prescribed orlistat. Which of the following statements indicates to the nurse that the client understands the teaching?

A. Liver function tests: While lithium can affect liver function in some cases, routine liver function tests are not typically required before administering lithium. These tests are more relevant for medications metabolized by the liver.
B. Thyroid hormone assay: This is the correct action. Regular monitoring of thyroid function, including thyroid hormone levels, is essential for clients taking lithium, as lithium therapy can lead to hypothyroidism or exacerbate preexisting thyroid conditions. Checking thyroid function before administering lithium helps ensure the client's thyroid status is within the therapeutic range and identifies any abnormalities that may require intervention.
C. Erythrocyte sedimentation rate (ESR): ESR is a nonspecific marker of inflammation and is not directly relevant to monitoring lithium therapy. While lithium can affect renal function and electrolyte balance, ESR does not specifically assess these parameters.
D. Brain natriuretic peptide (BNP): BNP is a marker of cardiac function and is not routinely monitored in clients taking lithium. While lithium can have cardiovascular effects, routine BNP testing is not necessary before administering lithium. Monitoring for cardiovascular side effects of lithium typically involves assessing for symptoms such as arrhythmias or changes in blood pressure and heart rate.

A. This statement reflects guilt or concern over potential harm to the child, which may be distressing but does not specifically indicate symptoms of PTSD related to combat exposure.
B. This statement describes nightmares or intrusive thoughts related to traumatic events, which are common symptoms of PTSD. The content of the dreams suggests re-experiencing of traumatic events, which is characteristic of PTSD.
C. This statement reflects hypervigilance and paranoia, common symptoms of PTSD. The client's behavior of checking rooms for potential threats indicates a heightened state of arousal and persistent fear related to past combat experiences.
D. While involvement in combat and actions such as killing enemy soldiers may contribute to the development of PTSD, this statement does not directly reflect symptoms of the disorder. Instead, it describes a specific event from the client's military experience. Symptoms of PTSD typically involve re-experiencing, avoidance, negative changes in mood and cognition, and hyperarousal.
