A nurse is providing discharge instructions to a client who has asthma and is about to start taking theophylline (Theo-24). The nurse should tell the client that this medication might cause which of the following adverse effects?
Tachycardia
Drowsiness
Constipation
Oliguria
The Correct Answer is A
Choice A reason: Tachycardia is a possible adverse effect of theophylline, as it is a methylxanthine that stimulates the central nervous system and the cardiac muscle. The nurse should instruct the client to monitor their pulse rate and report any palpitations, chest pain, or irregular heartbeat.
Choice B reason: Drowsiness is not a likely adverse effect of theophylline, as it is a stimulant that increases alertness and energy. The nurse should caution the client to avoid taking the medication close to bedtime, as it may cause insomnia.
Choice C reason: Constipation is not a common adverse effect of theophylline, as it does not affect the gastrointestinal motility or secretion. The nurse should advise the client to maintain a balanced diet, adequate fluid intake, and regular exercise to prevent constipation.
Choice D reason: Oliguria is not a typical adverse effect of theophylline, as it does not impair the renal function or cause fluid retention. The nurse should encourage the client to drink enough fluids to prevent dehydration and maintain a normal urine output.

Correct Answer is ["A","C"]
Explanation
Choice A reason: Tremors are a common sign of hypoglycemia, which occurs when the blood glucose level drops below 70 mg/dL. Hypoglycemia can cause shakiness, nervousness, and anxiety.
Choice B reason: Polydipsia, or excessive thirst, is not a manifestation of hypoglycemia, but rather of hyperglycemia, which occurs when the blood glucose level is too high. Hyperglycemia can cause dehydration, dry mouth, and increased urination.
Choice C reason: Confusion is another common sign of hypoglycemia, which can affect the brain's function and cognition. Hypoglycemia can cause dizziness, headache, difficulty concentrating, and impaired judgment.
Choice D reason: Polyphagia, or excessive hunger, is also not a manifestation of hypoglycemia, but rather of hyperglycemia. Hyperglycemia can cause the body to break down muscle and fat for energy, resulting in weight loss and increased appetite.
Choice E reason: Polyuria, or excessive urination, is also not a manifestation of hypoglycemia, but rather of hyperglycemia. Hyperglycemia can cause the kidneys to excrete excess glucose in the urine, leading to fluid loss and electrolyte imbalance.
Correct Answer is B
Explanation
Choice A reason: Benzonatate is not the correct answer. Benzonatate is a cough suppressant that works by numbing the throat and lungs. It does not help in the removal of mucus.
Choice B reason: Guaifenesin is the correct answer. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the airways. It helps in the removal of mucus by making it easier to cough up.
Choice C reason: Diphenhydramine is not the correct answer. Diphenhydramine is an antihistamine that works by blocking the effects of histamine, a chemical that causes allergy symptoms. It does not help in the removal of mucus.
Choice D reason: Dextromethorphan is not the correct answer. Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. It does not help in the removal of mucus.
