A nurse is about to administer Propanolol to a patient. The nurse takes the patient's apical pulse and documents it as 58 bmp. How should the nurse continue?

Correct Answer: D

Rationale: The correct answer is D: Withhold administration of the medication and notify the physician. An apical pulse of 58 bmp indicates bradycardia, which is a contraindication for Propranolol, a beta-blocker that can further reduce heart rate. By withholding the medication and informing the physician, the nurse ensures patient safety and avoids potential harm. Cutting the tablet in half (choice B) or giving the XR form (choice C) would still expose the patient to the medication, risking adverse effects. Administering the medication as normal (choice A) would be unsafe due to the already low heart rate.

Correct Answer: C

Rationale: The correct answer is C: Vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Therefore, the antidote for Warfarin is vitamin K, as it helps restore the clotting factors to their normal activity levels. Vitamin D (choice A), Vitamin C (choice B), and Vitamin B (choice D) do not have a direct role in counteracting the effects of Warfarin and are thus incorrect choices.

Correct Answer: C

Rationale: The correct answer is C: Assess weight. Before administering levothyroxine, the nurse should assess the patient's weight as levothyroxine dosage is often based on weight to ensure proper dosing. Monitoring weight helps in determining the appropriate dosage and adjusting it as needed. Assessing the degree of numbness in an affected area (A) and monitoring for intensified pain (B) are not directly related to levothyroxine administration. Assessing the apical pulse (D) may be important in some cases, but weight assessment is specifically crucial for determining the correct dosage of levothyroxine.

Correct Answer: A

Rationale: The correct answer is A: Laxative. Senna is classified as a laxative due to its mechanism of action in stimulating bowel movements. Senna contains compounds that act on the colon to increase fluid secretion and promote peristalsis, aiding in relieving constipation. Choices B, C, and D are incorrect. B: Anti-Ulcer drugs like proton pump inhibitors or H2 blockers are used to treat ulcers by reducing stomach acid production. C: ACE inhibitors are used to treat high blood pressure by blocking an enzyme that constricts blood vessels. D: Benzodiazepines are a class of drugs used to treat anxiety, insomnia, and seizures by enhancing the effects of the neurotransmitter GABA.

Correct Answer: B

Rationale: The correct answer is B: pre and post prandial advice. This section in MIMS provides guidance on how food can affect the absorption and efficacy of drugs. It includes recommendations on whether to take medication with or without food, which can impact drug effectiveness. Choice A, Preg. Cat, focuses on pregnancy category classification of drugs. Choice C, drug category, categorizes drugs based on their therapeutic class. Choice D, abbreviations, lists common medical abbreviations used in drug prescribing. Therefore, the correct answer B is the most relevant section for understanding the effect of food on drugs in MIMS.
