Correct Answer: B

Rationale: Mild headaches during pregnancy can be common and are often related to stress and tension. Recommending conscious relaxation techniques daily can help to relieve tension, reduce stress, and alleviate headaches without the need for medication, which is safer during pregnancy. Choice A is incorrect as ibuprofen is not recommended during pregnancy due to potential risks to the fetus. Choice C is incorrect because ginseng tea is not recommended during pregnancy as it may have adverse effects. Choice D is incorrect as soaking in a hot bath with a water temperature of 105°F can raise the body temperature, which is not safe during pregnancy.

Correct Answer: A

Rationale: Idiopathic thrombocytopenic purpura (ITP) is characterized by an autoimmune response that leads to a decreased platelet count. This condition increases the risk of bleeding due to the low platelet levels. Monitoring the platelet count is crucial in managing ITP, as it helps determine the risk of bleeding and guides treatment decisions. Therefore, the correct finding to expect in a client with ITP is a decreased platelet count. Choice B, an increased erythrocyte sedimentation rate (ESR), is not typically associated with ITP. Choice C, decreased megakaryocytes, may be seen in conditions like aplastic anemia but are not a typical finding in ITP. Choice D, an increased white blood cell count (WBC), is not a characteristic feature of ITP.

Correct Answer: B

Rationale: Chloasma, also known as the mask of pregnancy, is a blotchy, brown hyperpigmentation of the skin over the cheeks, nose, and forehead. It is most common in dark-skinned women and is caused by an increase in melanotropin during pregnancy. This condition typically appears after 16 weeks of gestation and gradually increases until delivery for 50 to 70% of women. The nurse should reassure the client that this is an expected occurrence, which usually fades after delivery. Therefore, explaining to the client that this is an expected occurrence is the appropriate action in this situation. Options A, C, and D are incorrect because chloasma is a common skin change during pregnancy and does not require a referral to a dermatologist, an increase in vitamin D intake, or suspicion of an allergy to skin care products.

Correct Answer: B

Rationale: In a client with uterine hypotonicity and postpartum hemorrhage, the priority is to address the risk of hypovolemic shock, which can lead to vital organ perfusion compromise and potentially death. Massaging the client's fundus helps to control bleeding by promoting uterine contraction and reducing blood loss, making it the nurse's priority intervention in this situation. Checking capillary refill may be important in assessing perfusion status but is not the priority over controlling the hemorrhage. Inserting an indwelling urinary catheter is not the priority in managing postpartum hemorrhage. Although preparing for a blood transfusion may be necessary, addressing the primary cause of bleeding by massaging the fundus takes precedence to stabilize the client's condition.

Correct Answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.
