A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client? 

Choice A reason: This is the correct action to include in the client's plan of care, as sucralfate should be given on an empty stomach, at least one hour before meals and at bedtime. Sucralfate is a mucosal protectant that forms a protective barrier over the ulcer and prevents further damage from acid and pepsin. It requires an acidic environment to work, so it should not be taken with food or antacids.

Choice B reason: This is not a relevant action to include in the client's plan of care, as sucralfate does not cause or increase the risk of secondary Candida infection. Candida infection is a fungal infection that can affect the mouth, throat, esophagus, or vagina. It is more common in clients who use antibiotics, corticosteroids, or immunosuppressants, but not sucralfate.

Choice C reason: This is not an accurate action to include in the client's plan of care, as sucralfate should be administered four times a day, not once a day. Sucralfate has a short duration of action, so it needs to be taken frequently to maintain its protective effect on the ulcer.

Choice D reason: This is not a necessary action to include in the client's plan of care, as sucralfate does not cause or affect electrolyte imbalance. Electrolyte imbalance is an abnormality in the levels of sodium, potassium, calcium, magnesium, or other minerals in the blood. It can be caused by dehydration, vomiting, diarrhea, kidney disease, or other conditions, but not sucralfate.

Choice A reason: Hypertension is not a typical sign of an allergic reaction to piperacillin-tazobactam, which is an antibiotic. It may be caused by other factors, such as pain, anxiety, or renal impairment. The nurse should monitor the client's blood pressure and report any abnormal findings.

Choice B reason: Bradycardia is not a common or serious side effect of piperacillin-tazobactam. It may be related to other medications, such as beta-blockers, or underlying cardiac conditions. The nurse should check the client's pulse and rhythm and report any changes.

Choice C reason: Pupillary constriction is not associated with piperacillin-tazobactam or an allergic reaction. It may be caused by other drugs, such as opioids, or neurological disorders. The nurse should assess the client's level of consciousness and pupillary response.

Choice D reason: Scratchy throat is a possible sign of anaphylaxis, which is a severe and potentially fatal allergic reaction to piperacillin-tazobactam or any other drug. Other symptoms may include hives, swelling, wheezing, or hypotension. The nurse should stop the infusion immediately and call for help.
