The nurse is working with a client who is newly diagnosed with hypothyroidism. Diagnostic testing has indicated that the client’s health problem is caused by anterior pituitary dysfunction.
This client’s hypothyroidism is rooted in a deficiency of:

tetraiodothyronine.

thyroid-stimulating hormone (TSH).

triiodothyronine.

Answer and Explanation

The Correct Answer is B

Thyroid-stimulating hormone - Wikipedia Thyroid-stimulating hormone (TSH) is a hormone produced by the anterior pituitary gland that stimulates the thyroid gland to release its own hormones, triiodothyronine (T) and thyroxine (T).12 If the anterior pituitary gland is dysfunctional, it will not produce enough TSH, leading to low levels of T and T. This condition is called secondary or pituitary hypothyroidism.123

Choice A is wrong because tetraiodothyronine is another name for thyroxine (T), which is a hormone produced by the thyroid gland, not the anterior pituitary gland.14

Choice C is wrong because triiodothyronine (T) is also a hormone produced by the thyroid gland, not the anterior pituitary gland.14

Normal ranges for TSH are 0.4 to 4.0 mIU/L, for T are 100 to 200 ng/dL, and for T are 4.5 to 11.2 mcg/dL.1

Correct Answer is B

Explanation

This is because antiemetics should be given to prevent motion sickness rather than after nausea or vomiting develop. Taking the medication 30 minutes before departing allows enough time for the drug to be absorbed and reach its peak effect.

Choice A is wrong because avoiding eating or drinking for 6 hours before the trip may cause dehydration and low blood sugar, which can worsen nausea and vomiting.

It is better to eat a light meal or snack before the trip and avoid spicy, greasy, or acidic foods.

Choice C is wrong because taking two doses if relief is not achieved may cause overdose and adverse effects.

Antiemetics should be taken as prescribed and not exceeded without consulting a doctor.

Choice D is wrong because increasing fluid intake to prevent urinary retention is not relevant for motion sickness.

Urinary retention is a possible side effect of some antiemetics, such as anticholinergics, but it is not a common problem for most people.

Fluid intake should be moderate and not excessive to avoid stomach distension.

A. “It increases the risk for low blood glucose levels.”. B. “There is no reason ginseng cannot be taken by people with diabetes.”. C. “There is no research to indicate what effect it will have.”. D. “It increases the risk for high blood glucose levels.”.

Correct Answer is A

Explanation

Ginseng is a herbal supplement that may have some antidiabetic effects, such as improving glucose tolerance and insulin resistance. However, ginseng may also interact with certain diabetes medications, especially insulin and sulfonylureas, and cause hypoglycemia (low blood sugar)2. Therefore, the nurse should inform the client about this potential risk and advise them to consult their doctor before taking ginseng.

Choice B is wrong because there is a reason ginseng cannot be taken by people with diabetes without medical supervision.

As explained above, ginseng may lower blood glucose levels too much and cause hypoglycemia.

Choice C is wrong because there is some research to indicate what effect ginseng will have on diabetes.

Several studies have shown that ginseng may have beneficial effects on blood glucose control, but also some adverse effects such as hypoglycemia.

Choice D is wrong because ginseng does not increase the risk for high blood
