Correct Answer: B

Rationale: The most crucial finding to report to the healthcare provider in this scenario is a serum potassium level of 3.1 mEq/L. Hypokalemia can lead to serious complications, including cardiac issues. Gastric output, increased BUN, and monitoring the 24-hour intake are essential but do not pose an immediate risk as hypokalemia does in this situation.

Correct Answer: C

Rationale: An A1C level of 6.5% indicates good long-term control of diabetes as it reflects the average blood sugar levels over the past 2-3 months. Monitoring fasting blood sugar provides immediate information about the current blood sugar level, while the absence of urine ketones indicates short-term control. Although the absence of diabetic ketoacidosis is positive, it doesn't specifically reflect long-term control like the A1C level does.

Correct Answer: B

Rationale: The correct answer is B. When reporting to the healthcare provider about a client's need for a belt restraint, it is crucial to provide information on the measures already taken to maintain client safety. This includes detailing alternative strategies that have been tried before considering restraint use. This information helps the healthcare provider assess the situation comprehensively and explore other safety interventions. Choices A, C, and D, though relevant to the client's care, are not as critical to report when discussing the need for a belt restraint. Pressure ulcers (Choice A) are important but not directly related to the need for a belt restraint. The presence of special mattresses (Choice C) may influence overall care but is not the most pertinent information when considering restraints. Current vital signs and oxygen saturation (Choice D) are essential for the client's overall assessment but do not directly address the need for a belt restraint.

Correct Answer: A

Rationale: The correct response is A: 'Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely.' Heparin is an anticoagulant that prevents further clot formation, but it does not quickly dissolve existing clots. It is crucial for the nurse to educate the client about the purpose of heparin and the necessity for close monitoring of bleeding risks. Choice B is incorrect as it does not address the misunderstanding about heparin's mechanism of action. Choice C is incorrect as home administration of IV heparin therapy requires careful consideration and should not be suggested without a thorough assessment. Choice D is incorrect as it does not address the client's misconception about heparin's role in dissolving clots and instead focuses on the client's desire to leave the hospital.

Correct Answer: B

Rationale: The most important action to take in this situation is to record 'no known drug allergies' on the preoperative checklist. This ensures that all healthcare staff involved in the surgery are aware of the client's stated lack of drug allergies, helping to prevent any potential adverse reactions. Assessing the client's knowledge of an allergic response (Choice A) may be valuable but is not the most crucial action at this point. Flagging 'no known drug allergies' on the front of the chart (Choice C) is less practical and visible compared to documenting it on the preoperative checklist. Assessing the client's allergies to non-drug substances (Choice D) is not the priority in this scenario where the focus is on medications due to the upcoming surgery.
