What instruction should the nurse give regarding the adverse effect of dry mouth associated with diphenhydramine for a client with poison ivy?
- A. Administer the medication with food.
- B. Chew on sugarless gum or suck on hard, sour candies.
- C. Place a humidifier at your bedside every evening.
- D. Discontinue the medication and notify your provider.
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.

Advil, Motrin, and Nuprin are examples of
- A. chemical names
- B. combination names
- C. trade names
- D. generic names
Correct Answer: C
Rationale: Advil, Motrin, and Nuprin are trade (brand) names for ibuprofen, marketed by different companies, distinct from its generic name (ibuprofen) or chemical name (e.g., 2-(4-isobutylphenyl)propanoic acid). Combination names aren't a category. Trade names reflect commercial branding, familiar to clients, a key distinction in pharmacology.
To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
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.
Which one of the following antipsychotics has been shown to be a partial agonist at the dopamine D2 receptor?
- A. Aripiprazole
- B. Clozapine
- C. Haloperidol
- D. Risperidone
Correct Answer: A
Rationale: Aripiprazole, a third-generation antipsychotic, acts as a partial agonist at D2 receptors, stabilizing dopamine activity: it activates receptors in low-dopamine states (e.g., negative symptoms) and competes with excess dopamine (e.g., psychosis), reducing side effects like EPS. Clozapine, a second-generation drug, has weak D2 affinity, targeting 5HT2 and other receptors. Haloperidol, a first-generation antipsychotic, is a D2 antagonist. Risperidone and thioridazine block D2 fully, not partially. Aripiprazole's unique partial agonism, confirmed by pharmacological data, balances efficacy and tolerability, distinguishing it in schizophrenia treatment.
A client has a prescription for Erythromycin. Which of the following instructions should be included?
- A. Take the medication with food.
- B. Expect your urine to turn dark yellow.
- C. Take the medication with a full glass of milk.
- D. Report persistent diarrhea to your provider.
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.
A nurse is completing discharge teaching for a client who has a new prescription for transdermal patches. Which of the following statements should the nurse identify as an indication that the client understands the instructions?
- A. "I will clean the site with an alcohol swab before I apply the patch."
- B. "I will rotate the application sites weekly."
- C. "I will apply the patch to an area of skin with no hair."
- D. "I will place the new patch on the site of the old patch.
Correct Answer: B
Rationale: Rotating the application sites of transdermal patches is important to prevent skin irritation and enhance absorption efficiency. This practice helps to minimize skin irritation and allows the skin to recover between applications. By rotating the sites weekly, the client can ensure optimal medication delivery and reduce the risk of skin reactions at any specific application site. This indicates that the client understands the importance of proper patch placement and skin care.
