Rationale: Cefazolin is a cephalosporin antibiotic, which has a cross-sensitivity with penicillin. Therefore, the nurse should ask the client about any previous reactions to cephalosporins before giving the medication.

Option B is incorrect because an antihistamine will not prevent a severe allergic reaction, such as anaphylaxis, which requires epinephrine.

Option C is incorrect because monitoring vital signs after the injection is not enough to prevent or treat an allergic reaction.

Option D is incorrect because diluting the medication will not affect its potential to cause an allergic reaction.

Rationale: Epinephrine is the first-line medication for anaphylaxis, as it reverses bronchoconstriction, vasodilation, and edema that can compromise the airway and circulation.

Option B is incorrect because diphenhydramine is an antihistamine that can help relieve itching and hives, but it does not act fast enough to treat anaphylaxis.

Option C is incorrect because albuterol is a bronchodilator that can help with wheezing, but it does not address the other manifestations of anaphylaxis. Option

D is incorrect because prednisone is a corticosteroid that can help reduce inflammation, but it has a delayed onset of action and is not effective for acute anaphylaxis.

Rationale: Lisinopril is an ACE inhibitor that can cause a dry cough as a common side effect. The nurse should notify the provider and request a prescription for an ARB, which has a similar antihypertensive effect but does not cause a dry cough.

Option A is incorrect because drinking more fluids and using lozenges may not relieve the cough caused by lisinopril.

Option B is incorrect because switching to another ACE inhibitor will likely result in the same side effect.

Option D is incorrect because stopping lisinopril abruptly can cause rebound hypertension and worsen the client's condition.
