Correct Answer: C

Rationale: The most life-threatening adverse reaction associated with Omeprazole is Clostridium difficile-associated diarrhea. This condition can be severe and life-threatening due to the potential for dehydration, electrolyte imbalances, and complications such as toxic megacolon. Chest pain, constipation, and acute interstitial nephritis are potential side effects of Omeprazole but are not considered as life-threatening as Clostridium difficile-associated diarrhea. Monitoring for signs of this adverse reaction is crucial, and immediate medical attention should be sought if symptoms develop.

Correct Answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

Correct Answer: B

Rationale: The correct instruction for dry mouth associated with diphenhydramine is to chew on sugarless gum or suck on hard, sour candies. These actions stimulate saliva production, providing relief from dry mouth. Administering the medication with food (Choice A) may help reduce stomach upset but won't address dry mouth. Placing a humidifier at the bedside (Choice C) can help with dry air-related issues but won't specifically target dry mouth. Discontinuing the medication (Choice D) without consulting the provider is not recommended and may lead to inadequate treatment of poison ivy.

Correct Answer: C

Rationale: When a nurse detects a hematoma at the IV catheter insertion site, applying warm compresses is beneficial as it can promote healing by enhancing circulation and reducing swelling. Elevating the client's arm helps in reducing edema, which can relieve pressure, pain, and further bleeding in the hematoma area. Stopping the infusion may be necessary in certain situations, but it is not a standard action for all hematoma cases. Applying alcohol to the insertion site is discouraged as it can cause irritation and may not aid in resolving the hematoma.

Correct Answer: D

Rationale: The correct answer is D: 'Report persistent diarrhea to your provider.' Erythromycin is known to cause Clostridium difficile-associated diarrhea, which can be severe. Instructing the client to report any persistent diarrhea to their healthcare provider promptly is crucial to prevent complications. Choices A, B, and C are incorrect. Taking Erythromycin with food is generally recommended to reduce stomach upset, but it is not the most critical instruction. Expecting urine to turn dark yellow is not a common side effect of Erythromycin. Taking Erythromycin with a full glass of milk is not necessary and may not be appropriate for all clients, especially those with lactose intolerance or dairy allergies.
