ATI N180 Pharmacology Quiz 2 | Nurselytic

Correct Answer: D

Rationale: Rationale for Correct Answer (
D): Cimetidine (Tagamet H
B) is a histamine-2 receptor antagonist commonly used to treat peptic ulcer disease. One of the side effects of cimetidine is sexual dysfunction, including decreased libido in males.
Therefore, it is important for the nurse to include this information in the teaching to ensure the client is aware of potential side effects and can seek medical advice if needed.

Summary of Incorrect

Choices:
A: This medication does not typically cause increased libido; in fact, it is more commonly associated with decreased libido.
B: Cimetidine should not be taken with antacids as they can reduce its effectiveness.
C: Cimetidine does not neutralize stomach acid; it works by blocking histamine-2 receptors to reduce acid production.
E, F, G: No additional choices provided, but they would be incorrect as they do not pertain to the effects of cimetidine on libido.

Correct Answer: A

Rationale: The correct answer is A: Hyperglycemia. The interaction between metformin and iodine-containing contrast dye can lead to lactic acidosis, a serious condition that can cause hyperglycemia. Metformin is excreted by the kidneys, and the contrast dye can impair kidney function, leading to metformin accumulation and lactic acidosis. Acute renal failure (
B), acute pancreatitis (
C), and acute liver failure (
D) are not directly associated with the interaction between metformin and contrast dye.

Correct Answer: A,B,C,D

Rationale: The correct answer is A, B, C, D. Metoclopramide (Reglan) can cause tardive dyskinesia and prolonged QT interval as complications. The IV form is indeed used for postoperative and chemotherapy-induced nausea, bowel intubation, and GI tract examination. Complications can also include sedation. The oral form is used for diabetic gastroparesis and GERD due to its prokinetic effects. These statements are true based on the pharmacological actions and indications of metoclopramide. Tardive dyskinesia is a known side effect and the IV form is commonly used for the mentioned purposes. Sedation can also occur due to its effects on the central nervous system. The oral form's mechanism of action supports its use for diabetic gastroparesis and GERD.

Correct Answer: B

Rationale: The correct answer is B: Thyrotoxicosis. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism. In some cases, excessive dosage can lead to thyrotoxicosis, characterized by symptoms such as diarrhea, weight loss, palpitations, and heat intolerance. This occurs when the thyroid hormone levels become too high in the body, causing an overactive thyroid state.


Choice A, hypothyroidism, is incorrect because the client is already being treated for hypothyroidism with levothyroxine.

Choices C (Addison's Disease) and D (Cushing's Disease) are unrelated conditions caused by dysfunction of the adrenal glands, not the thyroid.
Therefore, they are incorrect.

Correct Answer: A,E

Rationale: The correct answer is A and E. Weight gain can be a side effect of glipizide due to its mechanism of action increasing insulin secretion, which can lead to increased fat storage. Hyperglycemia can occur as a complication if the dosage of glipizide is too high or if the client's diet or exercise regimen is not properly managed.
Choice B is incorrect because weight loss is not a common side effect of glipizide.
Choice C, GI side effects, are possible with glipizide but not as common as the other complications listed.
Choice D, hypoglycemia, is a potential complication of glipizide due to its ability to lower blood sugar levels.
Choice F, hypertriglyceridemia, is not typically associated with glipizide use.
