For which client would the use of a phenothiazine most likely be contraindicated?

A client being treated for a traumatic brain injury.

A client with a history of ischemic heart disease.

A pediatric client.

A client with type 2 diabetes.

Answer and Explanation

The Correct Answer is A

Phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines are a class of drugs that have antipsychotic, antiemetic, and sedative effects. They act by blocking dopamine receptors in the brain and can cause extrapyramidal symptoms, hypotension, and anticholinergic effects.

Choice B is wrong because phenothiazines are not contraindicated in patients with ischemic heart disease.

However, they can cause orthostatic hypotension and cardiac arrhythmias, so they should be used with caution and monitored closely in these patients.

Choice C is wrong because phenothiazines are not contraindicated in pediatric patients.

However, they can cause sedation, hypotension, and extrapyramidal symptoms, so they should be used with caution and at lower doses in these patients.

Choice D is wrong because phenothiazines are not contraindicated in patients with type 2 diabetes.

However, they can cause hyperglycemia and weight gain, so they should be used with caution and monitored closely in these patients.

Correct Answer is A

Explanation

Diaphoresis means excessive sweating, which is one of the symptoms of hypoglycemia. Hypoglycemia occurs when the blood sugar level is lower than the normal range, which can cause dizziness, confusion, weakness, hunger, and other signs.

Choice B is wrong because flushing of the face is not a symptom of hypoglycemia.

Flushing can be caused by other conditions, such as fever, allergic reactions, or rosacea.

Choice C is wrong because fruity breath is a symptom of hyperglycemia, not hypoglycemia.

Hyperglycemia means high blood sugar level, which can cause the body to produce ketones that give the breath a fruity odor.

Choice D is wrong because unpredictable behaviors are not a specific symptom of hypoglycemia.

However, hypoglycemia can cause confusion, irritability, or anxiety, which may affect the behavior of some people.

The normal range of blood sugar level for most people is between 70 and 130 mg/dL (3.9 and 7.2 mmol/L) before meals and less than 180 mg/dL (10 mmol/L) after meals.

However, this may vary depending on the individual and the type of diabetes.

It is important to monitor the blood sugar level regularly and treat hypoglycemia promptly by eating or drinking a simple sugar source.

A. Number of times client’s family reports the client is nauseated. B. How well the client is eating. C. Color and amount of vomit, and frequency of vomiting episodes. D. Client’s nutritional status and fluid balance.

Correct Answer is C

Explanation

The nurse would assess these factors to determine the need for therapy. Some possible explanations for the other choices are:

Choice A. Number of times client’s family reports the client is nauseated.

This is not a reliable indicator of the severity or cause of nausea and vomiting.

The nurse should assess the client directly and not rely on the family’s reports.

Choice B. How well the client is eating.

This is not a specific or objective measure of nausea and vomiting.

The client may have other reasons for not eating well, such as loss of appetite, taste changes, or pain.

The nurse should also monitor the client’s weight, hydration status, and electrolyte levels.

Choice D. Client’s nutritional status and fluid balance.

These are important aspects of the client’s overall health, but they are not directly related to nausea and vomiting.

The nurse should assess these factors as part of the comprehensive care plan, but they are not sufficient to determine the need for therapy.
