Correct Answer: A

Rationale: The correct answer is A: Increased risk of bleeding. Edoxaban is an anticoagulant that works by inhibiting clot formation, thereby increasing the risk of bleeding. Therefore, the nurse should closely monitor the client for signs of bleeding, such as bruising, petechiae, hematuria, or gastrointestinal bleeding, to prevent potential complications.

Correct Answer: C

Rationale: The practical nurse (PN) should instruct the client to complete the full course of the antibiotic to ensure the infection is fully treated and to prevent the development of antibiotic resistance. Completing the full course of antibiotics helps to eradicate the infection completely and reduces the risk of bacteria developing resistance to the medication.

Correct Answer: C

Rationale: When a client with chronic heart failure is prescribed furosemide, a diuretic, the nurse should be vigilant for potential adverse effects. Furosemide can lead to excessive fluid loss, resulting in dehydration. Dehydration is a significant concern as it can exacerbate heart failure symptoms. Additionally, furosemide can cause electrolyte imbalances, particularly affecting potassium and sodium levels. Monitoring for signs of dehydration and electrolyte disturbances is crucial to prevent complications and ensure the client's safety and well-being.

Correct Answer: D

Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is essential to manage their glucose levels effectively. In this scenario, the best approach is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications.

Correct Answer: C

Rationale: The correct answer is C. It is crucial for the nurse to obtain information regarding the client's pregnancy status before administering misoprostol, as this medication is contraindicated in pregnancy due to its potential to cause uterine contractions. This can lead to serious complications such as miscarriage or premature birth. Therefore, assessing whether the client is currently pregnant is essential to ensure the safe administration of misoprostol.
