Correct Answer: D

Rationale: When educating a client about medroxyprogesterone, it is important to include information about potential side effects and recommendations. Weight fluctuations and irregular vaginal spotting are common side effects of medroxyprogesterone. Additionally, increasing calcium intake is often advised to counteract the potential bone density loss associated with this medication. Therefore, all the statements provided are correct, making option D the correct answer. Choices A, B, and C are all essential pieces of information that the healthcare provider should convey to the client regarding medroxyprogesterone.

Correct Answer: B

Rationale: During the first few months of pregnancy, it is common for individuals to experience mixed feelings due to hormonal changes and the significant life adjustments that come with pregnancy. The nurse's response should acknowledge the client's feelings as normal and provide reassurance rather than dismissive or directive statements. By acknowledging the normalcy of these emotions, the nurse validates the client's experience and offers support during this critical time. Choices A, C, and D are less appropriate. Choice A focuses on informing the provider without addressing the client's emotions directly. Choice C disregards the client's current feelings and imposes a specific emotional response. Choice D jumps to scheduling a counseling appointment without first acknowledging the client's emotions or providing immediate support and validation.

Correct Answer: D

Rationale: Calcium gluconate is the antidote for magnesium sulfate toxicity. In cases of magnesium sulfate toxicity, calcium gluconate is administered to counteract the effects of magnesium and restore calcium levels. Magnesium toxicity can lead to symptoms such as muscle weakness, respiratory depression, and cardiac arrhythmias. Calcium gluconate helps in reversing these effects by competing with magnesium and preventing its adverse manifestations. Nifedipine is a calcium channel blocker used for conditions like hypertension and angina, not for magnesium toxicity. Pyridoxine is vitamin B6 and is not the antidote for magnesium toxicity. Ferrous sulfate is an iron supplement and is not used to treat magnesium sulfate toxicity.

Correct Answer: D

Rationale: The correct answer is D, 'All of the Above.' Magnesium sulfate should not be used in cases of fetal distress, vaginal bleeding, or cervical dilation greater than 6 cm. These conditions can be exacerbated by the administration of magnesium sulfate, leading to further complications for the client. Choice A, fetal distress, is a contraindication because magnesium sulfate can further affect the fetal heart rate. Choice B, cervical dilation greater than 6 cm, is a contraindication as magnesium sulfate can potentially suppress uterine contractions, prolonging labor. Choice C, vaginal bleeding, is a contraindication as magnesium sulfate can further increase bleeding tendencies.

Correct Answer: C

Rationale: In this scenario, the symptoms of continued nausea, vomiting, scant prune-colored discharge, and a fundal height larger than expected at 4 months of gestation suggest a possible hydatidiform mole. Hyperemesis gravidarum (choice A) typically presents with severe nausea, vomiting, weight loss, and electrolyte imbalances. Threatened abortion (choice B) is characterized by vaginal bleeding with or without cramping but does not typically present with prune-colored discharge. Preterm labor (choice D) manifests with regular uterine contractions leading to cervical changes and can occur later in pregnancy.
