Question 1 of 5
A patient with elevated lipid levels has a new prescription for nicotinic acid (niacin). The nurse informs the patient that which adverse effects may occur with this medication?
Correct Answer: A
Rationale: Niacin, also known as nicotinic acid, is commonly associated with adverse effects of pruritus (itching) and cutaneous flushing (redness and warmth of the skin). These side effects are usually dose-related and can be alleviated by taking aspirin or a nonsteroidal anti-inflammatory drug (NSAID) 30 minutes before taking niacin. It's important for the nurse to inform the patient about these common side effects so that they are aware of what to expect and how to manage them if they occur.
Question 2 of 5
A 23-year-old man victim of a motor vehicle accident is brought to the emergency department. He is found to have a blood alcohol level of 850 mg/dL. Because of the way the body handles ethanol, the conventional 'half-life' to describe its metabolism does not apply. Which of the following drugs at therapeutic concentrations exhibits the same property?
Correct Answer: D
Rationale: Ethanol's zero-order metabolism matches phenytoin , saturating enzymes at therapeutic levels. Aspirin , ibuprofen , simvastatin , and valproic acid (E) follow first-order kinetics. Phenytoin's fixed-rate clearance mirrors ethanol's.
Question 3 of 5
A nurse is evaluating a client who is HIV positive who is prescribed with pentamidine (Pentam) IV for
Correct Answer: C
Rationale: Redness and pain at the site of the infusion can indicate a potential infiltration or extravasation of the medication, in this case, pentamidine (Pentam) IV. Pentamidine is a medication used to treat Pneumocystis jiroveci (formerly known as Pneumocystis carinii) pneumonia in HIV patients. Infiltration or extravasation of pentamidine can lead to tissue damage, necrosis, and potentially severe complications. Therefore, it is crucial to immediately assess and address any signs of redness and pain at the infusion site to prevent further harm to the patient. This assessment finding should be promptly relayed to the physician for further evaluation and intervention.
Question 4 of 5
Androgen is secreted by
Correct Answer: C
Rationale: Androgens, primarily testosterone, are secreted by the testes' Leydig cells, stimulated by luteinizing hormone (LH) from the pituitary, making the testes the direct source. Follicle-stimulating hormone (FSH) from the pituitary regulates sperm production, not androgen secretion. Gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers pituitary LH and FSH release, indirectly influencing androgen production, not secreting it. The pituitary releases LH and FSH, not androgens itself. The testes' role as the endocrine organ producing androgens is clear, driven by LH, and is fundamental to male reproductive and secondary sexual characteristics, setting it apart from regulatory hormones in the hypothalamic-pituitary-gonadal axis.
Question 5 of 5
The nurse is doing health teaching with a patient with psoriasis. Which nursing implication is a priority for a patient on infliximab to treat psoriasis?
Correct Answer: D
Rationale: Infliximab, a biologic agent used to treat psoriasis, can suppress the immune system and increase the risk of infections and blood disorders. Monitoring the complete blood count (D) is a priority to detect neutropenia, anemia, or thrombocytopenia. Monitoring weight (A), electrolytes (B), or urine output (C) is not typically associated with infliximab therapy.
