A client with coronary artery disease (CAD) is admitted to the medical unit for testing. The client describes having had frequent episodes of angina over the last few days prior to admission. The client is now experiencing shortness of breath, nausea, and chest pressure. After obtaining the client's vital signs, which action should the nurse take next?

A. Clonazepam is a benzodiazepine used primarily for anxiety disorders and can affect mental status, including cognition and level of alertness. Regular assessment helps monitor for any changes in mental status, such as drowsiness, confusion, or sedation, which are potential side effects of clonazepam.
B. This intervention helps maintain oral hygiene, which is important when a client is taking medications orally. Benzodiazepines like clonazepam can cause dry mouth as a side effect, which can contribute to oral hygiene issues such as increased risk of dental caries or oral infections.
C. Clonazepam itself does not directly affect calcium levels. Monitoring calcium levels is not a routine nursing intervention specifically related to clonazepam administration. This option is not appropriate in this context.
D. Clonazepam is not an opioid and does not directly interact with opioids in a way that would necessitate having an opioid agonist at the bedside. This option is not relevant for a client starting clonazepam.
E. Clonazepam can cause dizziness and impair coordination, especially when starting the medication or with dose changes. Assisting the client to the bathroom helps prevent falls and ensures safety, particularly if the client experiences dizziness or sedation.
F. Benzodiazepines like clonazepam can cause hypotension (low blood pressure), which may exacerbate upon standing (orthostatic hypotension). Screening involves checking blood pressure and heart rate in different positions (lying, sitting, standing) to detect orthostatic changes. This is important to prevent falls and other complications.

Rationale

A. Older adults are more susceptible to medication side effects due to changes in metabolism and polypharmacy. Reviewing the client's current medications, including over-the-counter medications for allergies and insomnia, can identify potential culprits.

B. Some medications used for allergies or insomnia, such as antihistamines or sedatives, can cause EPS in older adults. EPS include symptoms like tremors, rigidity, or involuntary movements. These symptoms can indicate adverse reactions that require immediate attention and adjustment of medication.

C. These symptoms could be side effects of medications commonly used for allergies and insomnia. They may also indicate other underlying health issues or medication interactions. Assessing these symptoms helps in determining their severity and whether they require further evaluation or intervention.

D. Social isolation can contribute to changes in behavior, especially in older adults. While social activities are beneficial for mental health, in this case, addressing the potential medication-related issues (options A and B) takes precedence to ensure the client's safety and well-being.
