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)
The Correct Answer is ["0.5"]
To calculate the number of tablets, the nurse should use the following formula:
Number of tablets = (Desired dose / Available dose) x (Available form / Desired form)
In this case, the desired dose is 50 mg, the available dose is 100 mg, the available form is 1 tablet, and the desired form is 1 tablet. Therefore, the formula becomes:
Number of tablets = (50 mg / 100 mg) x (1 tablet / 1 tablet)
Number of tablets = 0.5 x 1
Number of tablets = 0.5
The nurse should round the answer to the nearest tenth, which is 0.5. The nurse should use a leading zero if the answer is less than 1, which is 0.5. The nurse should not use a trailing zero, which means 0.5 and not 0.50.

Correct Answer is C
Explanation
Choice A reason: Prostaglandin E2 is not an appropriate medication for the client, because it is a uterotonic agent that stimulates uterine contractions and cervical ripening. Prostaglandin E2 is used to induce labor, not to stop it.
Choice B reason: Methylergonovine is not an appropriate medication for the client, because it is a uterotonic agent that causes sustained uterine contractions and vasoconstriction. Methylergonovine is used to prevent or treat postpartum hemorrhage, not to stop preterm labor.
Choice C reason: Terbutaline is an appropriate medication for the client, because it is a tocolytic agent that relaxes the uterine smooth muscle and inhibits contractions. Terbutaline is used to delay preterm labor and prolong pregnancy.
Choice D reason: Oxytocin is not an appropriate medication for the client, because it is a uterotonic agent that stimulates uterine contractions and milk ejection. Oxytocin is used to augment labor, not to stop it.
Correct Answer is B
Explanation
Choice A reason: Administering oxygen via nasal cannula is not a necessary intervention for the client, unless she has signs of hypoxia, such as dyspnea, tachypnea, or cyanosis. Oxygen administration is not routinely indicated for clients with inevitable abortion.
Choice B reason: Offering option to view products of conception is an appropriate intervention for the client, because it can help her cope with the loss of pregnancy and facilitate the grieving process. The nurse should respect the client's decision and provide emotional support.
Choice C reason: Instructing the client to increase potassium-rich foods in the diet is not a relevant intervention for the client, unless she has signs of hypokalemia, such as muscle weakness, cramps, or arrhythmias. Potassium intake is not related to the cause or prevention of inevitable abortion.
Choice D reason: Maintaining the client in a Trendelenburg position is not a recommended intervention for the client, because it can increase the risk of aspiration, respiratory compromise, and venous congestion. Trendelenburg position is not effective in preventing or treating inevitable abortion.
