A nurse is teaching a client who reports taking gingko biloba to improve his memory. Which of the following adverse effects should the nurse include in the teaching?
Bleeding gums
Decreased alertness
Breast enlargement
Bad breath
The Correct Answer is A
Choice A reason: Bleeding gums is a possible adverse effect of taking gingko biloba, as it may increase the risk of bleeding by inhibiting platelet aggregation and interfering with clotting factors. Gingko biloba may also interact with other medications that affect bleeding, such as anticoagulants, antiplatelets, or NSAIDs. The nurse should advise the client to monitor for signs of bleeding, such as bruising, nosebleeds, or hematuria, and report them to the provider.
Choice B reason: Decreased alertness is not a likely adverse effect of taking gingko biloba, as it may have the opposite effect of enhancing cognitive function and memory. Gingko biloba may improve blood flow to the brain and protect against oxidative stress and neuronal damage. The nurse should inform the client that gingko biloba may take several weeks to show its benefits and that the evidence for its effectiveness is inconclusive.
Choice C reason: Breast enlargement is not a known adverse effect of taking gingko biloba, as it does not affect the hormonal levels or the breast tissue. Gingko biloba may have some estrogenic activity, but it is not significant enough to cause gynecomastia or breast tenderness. The nurse should assess the client for other possible causes of breast enlargement, such as medications, liver disease, or tumors.
Choice D reason: Bad breath is not a common adverse effect of taking gingko biloba, as it does not affect the oral hygiene or the digestive system. Gingko biloba may have a mild odor, but it is not unpleasant or persistent. The nurse should advise the client to maintain good oral care and to check for other possible causes of bad breath, such as infections, dental problems, or dietary factors.

Correct Answer is A
Explanation
Choice A reason: Giving the medication in the morning daily is a correct instruction, as it helps to prevent asthma attacks throughout the day and night. Montelukast is a leukotriene receptor antagonist that blocks the inflammatory response and bronchoconstriction caused by leukotrienes. Montelukast has a long duration of action and can be given once a day, preferably in the evening or at bedtime. However, for children who have exercise-induced asthma, the medication can be given in the morning to prevent exercise-induced bronchospasm.
Choice B reason: Administering the granules mixed with 20 oz of water is not a correct instruction, as it may reduce the absorption and effectiveness of the medication. Montelukast granules should be administered within 15 minutes of opening the packet and can be mixed with a small amount of soft food, such as applesauce, mashed carrots, or ice cream. The granules should not be mixed with liquids, such as water, juice, or milk, as they may dissolve and lose their potency.
Choice C reason: Giving the medication at the onset of wheezing is not a correct instruction, as it may not provide immediate relief of the symptoms and may delay the use of a rescue inhaler. Montelukast is not a bronchodilator and does not work quickly to open the airways. Montelukast is a preventive medication that should be taken regularly to reduce the frequency and severity of asthma attacks. The child should use a short-acting beta-agonist, such as albuterol, for the quick relief of wheezing.
Choice D reason: Administering the medication 2 hr before exercise is not a correct instruction, as it may not prevent exercise-induced bronchospasm and may interfere with the daily dosing schedule. Montelukast should be taken once a day, preferably in the evening or at bedtime, to provide consistent protection against asthma triggers. However, for children who have exercise-induced asthma, the medication can be given in the morning to prevent exercise-induced bronchospasm. The child should also use a short-acting beta-agonist before exercise, as needed.
Correct Answer is B
Explanation
Choice A reason: Blood pressure 160/94 mm Hg is not a reason to withhold atenolol, as it is a beta-blocker that lowers blood pressure and reduces the workload of the heart. Atenolol is indicated for hypertension, angina, and arrhythmias. The nurse should administer atenolol as prescribed, unless the blood pressure is too low (hypotension).
Choice B reason: Heart rate 46/min is a reason to withhold atenolol, as it is a sign of bradycardia (slow heart rate), which can be a side effect of atenolol. Atenolol can decrease the heart rate by blocking the beta-1 receptors in the heart. The nurse should withhold atenolol if the heart rate is below 60 beats per minute or above 100 beats per minute, and report the finding to the provider.
Choice C reason: Oxygen saturation 95% is not a reason to withhold atenolol, as it is a normal value that indicates adequate oxygenation of the blood. Atenolol does not affect the oxygen saturation or the respiratory function. The nurse should monitor the oxygen saturation regularly, and report any signs of hypoxia (low oxygen level).
Choice D reason: Respiratory rate 18/min is not a reason to withhold atenolol, as it is a normal value that indicates normal breathing. Atenolol does not affect the respiratory rate or the respiratory function. The nurse should monitor the respiratory rate regularly, and report any signs of dyspnea (difficulty breathing).
