A nurse is teaching a client about taking diphenhydramine. The nurse should explain to the client that which of the following is an adverse effect of this medication?
Headache
Constipation
Bradycardia
Hypertension
None
None
The Correct Answer is B
The correct answer is choice b. Constipation.
Choice A rationale:
While headaches can occur with some medications, they are not a common adverse effect of diphenhydramine. Diphenhydramine's typical side effects are more related to its anticholinergic properties.
Choice B rationale:
Diphenhydramine is an antihistamine with anticholinergic effects, which can lead to dry mouth, urinary retention, and constipation as common adverse effects.
Choice C rationale:
Diphenhydramine typically does not cause bradycardia. In some cases, it may cause tachycardia (increased heart rate) rather than a slower heart rate.
Choice D rationale:
Hypertension is not typically associated with diphenhydramine. In fact, it can sometimes cause hypotension (low blood pressure) rather than high blood pressure.

Correct Answer is D
Explanation
The intravenous route provides the most rapid onset of medication action because the medication is delivered directly into the bloodstream. However, this route also poses the greatest risk of adverse effects if the medication is administered incorrectly or too rapidly because there is no opportunity for the body to metabolize or excrete the medication before it reaches its target organs.
Correct Answer is C
Explanation
A.Cephalexin oral suspension should typically be stored in the refrigerator to maintain its stability and effectiveness. Storing it at room temperature could affect its potency.
B.Shaking the oral suspension is necessary to ensure the medication is evenly distributed before each dose, providing the client with the correct dosage of active ingredients. Failure to shake the suspension can result in uneven dosing.
C.Cephalexin is a cephalosporin antibiotic, and there is a potential for cross-sensitivity in clients who are allergic to penicillin. Up to 10% of people with a penicillin allergy may also be allergic to cephalosporins. Checking for a penicillin allergy helps prevent an adverse reaction, making it a critical safety measure before administering cephalexin.
D.While some antibiotics can cause gastrointestinal side effects, constipation is not a common adverse effect associated with cephalexin. The nurse should instead monitor for other side effects like diarrhea, which is more typical with antibiotics and can indicate a mild side effect or a more severe condition, such as Clostridioides difficile infection.
