Question 1 of 5
During the immediate postoperative recovery period, what is the nurse’s priority assessment?
Correct Answer: D
Rationale: The correct answer is D: Airway, breathing, and circulation. This is the priority assessment during the immediate postoperative recovery period as it ensures the patient's vital functions are stable. Assessing the airway ensures proper oxygenation, breathing status checks for any respiratory distress, and monitoring circulation helps detect any signs of shock or inadequate perfusion. Pupil responses (A) may indicate neurological changes but are not as critical as ensuring ABCs. Return to sensation (B) and level of consciousness (C) are important assessments but come after ensuring the patient's airway, breathing, and circulation are stable.
Question 2 of 5
A patient is being discharged on anticoagulant therapy. The nurse will include in the patient-education conversation that it is important to avoid herbal products that contain which substance?
Correct Answer: B
Rationale: Step 1: Ginkgo is known to have anticoagulant properties. Step 2: Anticoagulant medications also thin the blood. Step 3: Combining ginkgo with anticoagulants can increase the risk of bleeding. Step 4: Therefore, it is crucial to avoid ginkgo-containing herbal products to prevent potential bleeding complications. Summary: A: Valerian does not have anticoagulant properties. C: Soy does not typically interfere with anticoagulant therapy. D: Saw palmetto is not known to increase bleeding risk with anticoagulants.
Question 3 of 5
When monitoring patients on antitubercular drug therapy, the nurse knows that which drug may cause a decrease in visual acuity?
Correct Answer: C
Rationale: The correct answer is C: ethambutol (Myambutol). Ethambutol is known to cause optic neuritis, leading to a decrease in visual acuity. This adverse effect is dose-dependent and more likely to occur with prolonged use. Rifampin (A), isoniazid (B), and streptomycin (D) do not typically cause visual disturbances. Rifampin may cause a harmless orange discoloration of bodily fluids. Isoniazid is known for hepatotoxicity and peripheral neuropathy. Streptomycin can lead to ototoxicity and nephrotoxicity. Therefore, ethambutol is the correct choice due to its association with visual acuity changes.
Question 4 of 5
Conjugation is:
Correct Answer: C
Rationale: Conjugation is the coupling of a drug with an endogenous substrate to facilitate its elimination from the body. This process involves the addition of specific molecules (such as glucuronic acid, sulfate, or amino acids) to the drug molecule, making it more water-soluble for easier excretion. Choice A is incorrect because conjugation does not involve drug reduction. Choice B is incorrect as conjugation does not involve drug oxidation. Choice D is incorrect as conjugation is not about solubilization in lipids but rather in water-soluble forms for excretion.
Question 5 of 5
Local anesthetics produce:
Correct Answer: B
Rationale: The correct answer is B: Blocking pain sensation without loss of consciousness. Local anesthetics work by blocking nerve impulses in a specific area, leading to loss of sensation without affecting consciousness. This is achieved by blocking sodium channels in the nerves. Option A is incorrect as local anesthetics do not cause amnesia or loss of consciousness. Option C is incorrect as it refers to the effects of sedatives, not local anesthetics. Option D is incorrect as a stupor or somnolent state indicates a decreased level of consciousness, which local anesthetics do not cause.
