Nursing Elites

1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?

• A. Press your finger on the inside corner of your eye for 1 minute after application.
• B. Apply the eye drops directly on the cornea.
• C. Drop the prescribed amount of medication into the center of the conjunctival sac.
• D. Wipe your eyes gently with a tissue immediately after application.

Correct answer: C

Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.

3. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and is experiencing muscle weakness. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: A

Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers by increasing acetylcholine levels at the neuromuscular junction, thereby helping to restore muscle strength. Naloxone is an opioid antagonist used to reverse opioid effects, not neuromuscular blockade. Dantrolene is a skeletal muscle relaxant used to treat malignant hyperthermia or neuroleptic malignant syndrome, not to reverse neuromuscular blockade. Vecuronium is a nondepolarizing neuromuscular blocking agent, like the one the client received, and is not used to reverse its effects.

4. Medications classified as angiotensin II receptor agents typically end in?

• A. Sartan
• B. Ase
• C. Olol
• D. Pril

Correct answer: A

Rationale: Angiotensin II receptor agents belong to the drug class called angiotensin II receptor blockers (ARBs). The generic names of ARBs usually end in -sartan, helping to identify this specific class of medications. Therefore, medications that end in -sartan are likely to be angiotensin II receptor agents. Choices B, C, and D are incorrect because drugs ending in -ase (like streptokinase), -olol (like propranolol), and -pril (like lisinopril) typically belong to different drug classes with distinct mechanisms of action.

5. A client has a prescription for gentamicin for the treatment of an infection. Which finding indicates a potential adverse reaction to the medication?

• A. Blood pressure 160/90 mm Hg
• B. Presence of red blood cells in the urine
• C. Urine output of 35 mL/hr
• D. Respiratory rate of 22/min

Correct answer: B

Rationale: The presence of red blood cells in the urine can indicate nephrotoxicity, which is a potential adverse effect of gentamicin. Gentamicin can cause damage to the kidneys, leading to the presence of red blood cells in the urine as a sign of renal impairment. Monitoring for this finding is crucial to detect and manage adverse reactions promptly. High blood pressure (Choice A) is not typically associated with gentamicin use. Low urine output (Choice C) is more suggestive of kidney injury rather than nephrotoxicity specifically related to gentamicin. Respiratory rate (Choice D) is not a common indicator of adverse reactions to gentamicin.
