A nurse is preparing to administer atenolol 50 mg PO daily to a client. The amount available is atenolol 100 mg/tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)

Choice A reason: This statement is correct, as betamethasone is a corticosteroid that is given to pregnant women who are at risk of delivering before 34 weeks of gestation. Betamethasone stimulates the production of surfactant, which is a substance that prevents the alveoli from collapsing and improves the lung function of the fetus.

Choice B reason: This statement is incorrect, as betamethasone does not affect the cervical dilation, which is a sign of labor progression. Betamethasone does not stop or delay labor, but rather reduces the complications of prematurity, such as respiratory distress syndrome, intraventricular hemorrhage, or necrotizing enterocolitis.

Choice C reason: This statement is incorrect, as betamethasone does not increase the fetal heart rate, which is a measure of fetal well-being. Betamethasone may cause transient fetal bradycardia, which is a decrease in the fetal heart rate, due to the increased vagal tone and blood pressure. The nurse should monitor the fetal heart rate and notify the provider if there are any signs of fetal distress.

Choice D reason: This statement is incorrect, as betamethasone is not used to stop preterm labor contractions, which are caused by the uterine muscle activity. Betamethasone does not have any tocolytic effect, which is the ability to inhibit uterine contractions. Other medications, such as magnesium sulfate, nifedipine, or indomethacin, may be used to stop preterm labor contractions.

Choice A reason: Nervousness is a common and expected side effect of terbutaline, which is a beta-2 adrenergic agonist that stimulates the sympathetic nervous system and relaxes the uterine smooth muscle. The nurse does not need to report this finding to the provider, but can provide reassurance and comfort to the client.

Choice B reason: Tremors are also a common and expected side effect of terbutaline, as it causes increased muscle activity and shakiness. The nurse does not need to report this finding to the provider, but can monitor the client's vital signs and electrolyte levels, and advise the client to avoid caffeine and other stimulants.

Choice C reason: Dyspnea is an uncommon and serious side effect of terbutaline, as it can indicate pulmonary edema, which is a life-threatening condition where fluid accumulates in the lungs and impairs gas exchange. The nurse should report this finding to the provider immediately and prepare for interventions, such as oxygen therapy, diuretics, or discontinuation of terbutaline.

Choice D reason: Headaches are also a common and expected side effect of terbutaline, as it causes vasodilation and increased blood flow to the brain. The nurse does not need to report this finding to the provider, but can administer analgesics as prescribed, and encourage the client to rest and hydrate.
