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)

Answer and Explanation

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.

A. Dipstick value of 3+ for protein in her urine B. Pitting pedal edema at the end of the day C. Weight gain of 0.5 kg during the past 2 weeks D. Blood pressure (BP) increase to 138/86 mm Hg

Correct Answer is A

Explanation

Choice A reason: Dipstick value of 3+ for protein in her urine is a sign of significant proteinuria, which is one of the diagnostic criteria for preeclampsia, along with hypertension. Proteinuria indicates renal damage and impaired glomerular filtration, which can lead to complications, such as oliguria, eclampsia, or HELLP syndrome.

Choice B reason: Pitting pedal edema at the end of the day is a common and expected finding in pregnancy, as it results from the increased blood volume, venous pressure, and fluid retention. Edema is not a reliable indicator of preeclampsia, unless it is severe, generalized, or sudden.

Choice C reason: Weight gain of 0.5 kg during the past 2 weeks is a normal and expected finding in pregnancy, as it reflects the growth and development of the fetus, placenta, and maternal tissues. Weight gain is not a reliable indicator of preeclampsia, unless it is excessive, rapid, or associated with edema.

Choice D reason: Blood pressure (BP) increase to 138/86 mm Hg is a mild elevation that may indicate gestational hypertension, but not preeclampsia, unless it is accompanied by proteinuria or other signs of organ dysfunction. The diagnostic threshold for preeclampsia is a BP of 140/90 mm Hg or higher on two occasions at least four hours apart.
