A nurse is educating a client about the sympathetic nervous system. Which of the following statements is correct?

A) Temperature and respiratory rate:
While monitoring temperature and respiratory rate are important aspects of a comprehensive assessment, they are not the priority assessments before administering metoprolol. Metoprolol is a beta-blocker primarily used to lower heart rate and blood pressure, so assessing the client's heart rate and blood pressure is more relevant.

B) Heart rate and blood pressure:
This is the correct answer. Before administering metoprolol, it is essential to assess the client's heart rate and blood pressure. Metoprolol is a beta-blocker medication that primarily affects heart rate and blood pressure. Monitoring these vital signs helps ensure that the medication is administered safely and effectively.

C) Level of consciousness and pain level:
Assessing the client's level of consciousness and pain level are important aspects of nursing care, but they are not the priority assessments before administering metoprolol. These assessments may be relevant depending on the client's overall condition and specific care needs, but they are not directly related to the action or side effects of metoprolol.

D) Oxygen saturation and respiratory rate:
Monitoring oxygen saturation and respiratory rate are important aspects of respiratory assessment, but they are not the priority assessments before administering metoprolol. While metoprolol can affect respiratory function as a potential side effect, its primary action is on heart rate and blood pressure. Therefore, assessing heart rate and blood pressure are more pertinent before administering this medication.

A) Migraines:
Pseudoephedrine is not contraindicated for migraines. In fact, it is sometimes used in combination with other medications to alleviate symptoms of sinus congestion associated with migraines.

B) Diverticulitis:
Pseudoephedrine is not contraindicated for diverticulitis. However, it may cause gastrointestinal side effects such as abdominal discomfort or constipation, which could exacerbate symptoms in individuals with diverticulitis. Therefore, caution should be exercised when using pseudoephedrine in these clients.

C) Hypertension:
This is the correct answer. Pseudoephedrine is a sympathomimetic drug that can cause vasoconstriction and increase blood pressure. Therefore, it is contraindicated in clients with hypertension or cardiovascular disease, as it may exacerbate these conditions and increase the risk of adverse cardiovascular events such as hypertensive crisis or stroke.

D) Eczema:
Pseudoephedrine is not contraindicated for eczema. However, it may cause dryness of the skin and exacerbate existing dermatological conditions. Clients with eczema should use pseudoephedrine cautiously and monitor for any worsening of their skin condition.
