A nurse is assessing a client who has a prescription for oral albuterol for the long-term management of asthma.
For which of the following adverse effects should the nurse monitor?
Nystagmus.
Tachycardia.
Drowsiness.
Oral fungal infections.
The Correct Answer is B
Choice A rationale
Nystagmus, an involuntary rhythmic eye movement, is not a recognized or common adverse effect of oral albuterol. Albuterol is a beta-2 adrenergic agonist primarily acting on bronchial smooth muscle to cause bronchodilation. Its side effects are typically related to sympathetic nervous system stimulation, not oculomotor dysfunction.
Choice B rationale
Tachycardia is a common adverse effect of oral albuterol due to its systemic absorption and stimulation of beta-1 adrenergic receptors in the heart, in addition to its primary beta-2 effects on the lungs. This leads to an increased heart rate (normal range 60-100 bpm) and can cause palpitations, especially in sensitive individuals or with higher doses.
Choice C rationale
Drowsiness is not a typical adverse effect of oral albuterol. In fact, due to its stimulant properties, albuterol is more likely to cause central nervous system excitation, leading to insomnia, nervousness, or tremors rather than sedation. Its action is to activate adrenergic pathways, which generally promote alertness.
Choice D rationale
Oral fungal infections, such as oral candidiasis (thrush), are commonly associated with inhaled corticosteroids, not oral albuterol. Inhaled corticosteroids suppress the local immune response in the oral cavity, allowing opportunistic fungal growth. Oral albuterol does not have immunosuppressive effects on the oral mucosa.

Correct Answer is D
Explanation
Choice A rationale
Ethinyl estradiol and norethindrone, a common oral contraceptive combination, can sometimes lead to weight gain rather than weight loss. This is often attributed to fluid retention and changes in appetite or metabolism, rather than a catabolic effect causing weight reduction.
Choice B rationale
Easy bruising is not a typical manifestation of ethinyl estradiol and norethindrone use. While some hormonal contraceptives can affect coagulation factors, leading to an increased risk of thrombosis, they do not generally cause increased capillary fragility or platelet dysfunction manifesting as easy bruising.
Choice C rationale
Oral contraceptives containing estrogen, such as ethinyl estradiol, can actually cause a slight increase in blood pressure in some individuals due to their effects on the renin-angiotensin-aldosterone system, leading to sodium and water retention. Low blood pressure is not a common adverse effect.
Choice D rationale
Breakthrough bleeding, or irregular uterine bleeding that occurs during hormone therapy, is a common adverse effect of combined oral contraceptives like ethinyl estradiol and norethindrone, especially during the initial cycles of use. It results from an imbalance in the hormonal effects on the endometrium.
Correct Answer is B
Explanation
Choice A rationale
Insulin lispro is a rapid-acting insulin used to manage hyperglycemia in clients with diabetes mellitus. Its primary mechanism involves facilitating glucose uptake into cells and inhibiting hepatic glucose production. It does not directly mitigate the adverse effects, such as myelosuppression and gastrointestinal issues, associated with topotecan, a topoisomerase I inhibitor used in chemotherapy.
Choice B rationale
Granisetron is a serotonin 5-HT3 receptor antagonist, primarily used to prevent nausea and vomiting induced by chemotherapy. It works by blocking serotonin's action on vagal nerve terminals and in the chemoreceptor trigger zone in the brainstem. This action effectively controls a common and distressing adverse effect of topotecan, thereby improving client comfort and compliance.
Choice C rationale
Magnesium sulfate is an electrolyte replacement and smooth muscle relaxant. It is used in conditions like pre-eclampsia, eclampsia, and hypomagnesemia. Its physiological effects involve stabilizing neuronal excitability and reducing uterine contractions. It is not indicated for the management of topotecan's adverse effects, which predominantly involve myelosuppression and gastrointestinal toxicity.
Choice D rationale
Prednisone is a corticosteroid with potent anti-inflammatory and immunosuppressive properties. It is used to treat various conditions, including autoimmune disorders, allergic reactions, and some cancers. While it can reduce inflammation, it does not specifically target the common adverse effects of topotecan, such as myelosuppression and gastrointestinal disturbances.
