Question 1 of 5
Which sign is common with hypocalcemia?
Correct Answer: D
Rationale: Hypocalcemia causes muscle spasms (tetany)-nerve hyperexcitability, per classic signs-unlike bruising (coagulation), hypertension (not direct), or wasting (chronic). Spasms dominate, per assessment.
Question 2 of 5
Which statement is accurate regarding medications that end up being secreted in bile?
Correct Answer: B
Rationale: Biliary secretion (e.g., rifampin) leads to fecal excretion for some drugs, while others recycle enterohepatically, prolonging action. Not all are fecal-bound-recirculation varies. Gallbladder stores bile, not metabolizes. Many drugs use bile, not rare. Recirculation reflects pharmacokinetics, affecting duration.
Question 3 of 5
A 22-year-old man has taken an overdose of sleeping pills after learning that he did not receive the job he has recently been interviewed for. He is found by his roommate conscious but not able to completely follow commands. The roommate calls the local poison control center. Instructions are given to self-administer syrup of ipecac while waiting for the rescue squad to respond. This agent has a mechanism of action that involves which of the following?
Correct Answer: B
Rationale: Syrup of ipecac induces vomiting in overdose. It stimulates the chemotactic trigger zone in the medulla-prompting emesis. Gag reflex stimulation is secondary. Suppressing pressures , gag reflex , or motor cortex (E) don't apply. Though less used now, ipecac's CNS action expels pills, aiding this acute scenario, distinct from mechanical or suppressive effects.
Question 4 of 5
A patient who reports severe seasonal allergies has been prescribed fluticasone (Flonase). The nurse providing medication information would collaborate with the prescriber if the patient makes which statement?
Correct Answer: B
Rationale: Fluticasone, a corticosteroid, is contraindicated with active infections (e.g., viral colds) due to immunosuppression risks . 'My kids have a head cold' suggests exposure, prompting nurse-prescriber collaboration to assess infection status. Licorice , psoriasis , and fruit don't contraindicate use. Choice B prioritizes safety, avoiding exacerbation of undetected infection.
Question 5 of 5
The nurse is aware that efficient absorption of calcium is assisted by
Correct Answer: D
Rationale: Calcium absorption in the small intestine relies heavily on vitamin D, which enhances the process by increasing the expression of calcium-binding proteins and improving gut uptake efficiency. Without adequate vitamin D, calcium absorption drops significantly, leading to potential bone health issues like osteoporosis or osteomalacia. Intrinsic factor, produced in the stomach, is critical for vitamin B12 absorption, not calcium, as it binds B12 for uptake in the ileum. Coenzymes, while involved in metabolic reactions, don't directly facilitate calcium absorption; their role is broader and unrelated to this specific process. Phosphorus, an abundant mineral, works with calcium in bone formation but doesn't enhance its absorption-in fact, excessive phosphorus can compete with calcium. Vitamin D's active form, calcitriol, regulates calcium levels by promoting its transport across intestinal cells, making it indispensable for maintaining skeletal integrity. This mechanism underscores why vitamin D deficiency impairs calcium utilization, distinguishing it from the other options, which lack a direct link to absorption efficiency.
