Question 1 of 5
What is the pharmacologic classification of Amlodipine
Correct Answer: D
Rationale: Amlodipine belongs to the pharmacologic class of calcium channel blockers. It works by inhibiting the influx of calcium ions into smooth muscle cells, leading to vasodilation and lower blood pressure. This medication is commonly used to treat hypertension (high blood pressure) and certain types of angina (chest pain). It is not a beta blocker, 5-HT3 antagonist, or nonopioid analgesic.
Question 2 of 5
What is the reaction of the body to high threshold mechanoreceptor?
Correct Answer: D
Rationale: High threshold mechanoreceptors are responsible for sensing mechanical stimuli such as pressure and touch. When these receptors are activated, one of the body's reactions is to produce analgesia, which refers to the relief of pain or a decreased sensitivity to painful stimuli. This analgesic effect is a protective mechanism that helps reduce the perception of pain in response to potentially harmful mechanical stimuli. Therefore, the reaction of the body to high threshold mechanoreceptors is often associated with analgesia rather than tolerance, withdrawal reflex, inflammation, or suppuration.
Question 3 of 5
Penicillin G has been prescribed for a patient. Which nursing intervention(s) should the nurse perform for this patient? (Select all that apply.)
Correct Answer: A
Rationale: Penicillin G is a beta-lactam antibiotic that can cause severe allergic reactions, including anaphylaxis. Having epinephrine on hand is crucial for managing such emergencies. Collecting a culture and sensitivity before the first dose ensures the infection is caused by a penicillin-susceptible organism. Mouth ulcers are not a common side effect of penicillin, but monitoring for superinfections like oral thrush is important. Limiting fluid intake to 1000 mL/day is incorrect, as adequate hydration helps maintain renal function and prevents crystalluria. No particular interventions are required is incorrect, as penicillin requires careful monitoring for efficacy and adverse effects.
Question 4 of 5
What assessment finding indicates to the nurse that timolol (Timoptic) has been effective?
Correct Answer: B
Rationale: Timolol and carteolol are available in an ophthalmic form of the drug for reduction of intraocular pressure in patients with open-angle glaucoma. A decrease in intraocular pressure would indicate it has been effective. Timolol can also be used to treat hypertension but an increase in blood pressure would indicate the drug was not effective. Reduced pulse rate and reduced angina would not be related to this drug, especially if it was given in ophthalmic form when very little of the drug is absorbed systemically.
Question 5 of 5
The nurse is reviewing the care plan with a patient using enteral nutrition (EN). Which interventions by the nurse are appropriate for this strategy? (Select all that apply.)
Correct Answer: A
Rationale: Checking gastric residuals (A) ensures proper gastric emptying and reduces aspiration risk. Elevating the bed (B) prevents reflux and aspiration. Reporting absent bowel sounds (D) is critical, as EN is contraindicated in ileus. Feeding bags and tubing should be changed every 24 hours, not 3 to 4 days (C).
