Correct Answer: C

Rationale: A weight gain of 2.3 kg (5 lb) in 1 week can indicate worsening preeclampsia due to fluid retention, which can lead to serious complications. This finding should be reported promptly to the provider for further assessment and intervention. Blood pressure of 140/90 mm Hg is high but may not be an immediate concern for a client with preeclampsia at 30 weeks. 1+ pitting edema in the lower extremities is common in pregnancy, especially in the third trimester, and may not be a significant finding in isolation. A mild headache can be a common symptom in pregnancy and may not be indicative of worsening preeclampsia unless accompanied by other concerning signs.

Correct Answer: A

Rationale: The correct method of administering insulin to a patient with diabetes is to administer it subcutaneously. Insulin is typically injected into the fatty tissue just below the skin, allowing for a slow and consistent absorption into the bloodstream. Administering insulin intramuscularly (Choice B) is not recommended as it can lead to unpredictable absorption rates and potential complications. Administering insulin intravenously (Choice C) is only done in specific medical settings and not for routine diabetes management. Administering insulin orally (Choice D) is ineffective as the stomach acid would break down the insulin before it can be absorbed.

Correct Answer: C

Rationale: The correct instruction is to take ferrous sulfate on an empty stomach to increase absorption. This is because taking it with food or dairy products like milk can reduce its absorption. Orange juice is not recommended as it may interfere with the absorption of iron. Taking ferrous sulfate on an empty stomach may cause gastrointestinal upset, but this can be minimized by gradually increasing the dose.

Correct Answer: A

Rationale: The correct answer is to monitor INR levels. INR levels are the most critical indicator for monitoring bleeding risk in patients on warfarin. INR stands for International Normalized Ratio and specifically measures the clotting tendency of the blood. Monitoring hemoglobin levels, potassium levels, or platelet count are not as directly relevant to assessing bleeding risk in patients on warfarin.
