After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?
- A. Slide the stethoscope across the sternum.
- B. Move the stethoscope to the mitral site.
- C. Listen with the bell at the same location.
- D. Observe the cardiac telemetry monitor.
Correct Answer: C
Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

A client is admitted for type 2 diabetes mellitus (DM) and chronic kidney disease (CKD). Which breakfast selection by the client indicates effective learning?
- A. Scrambled eggs, bacon, one slice of whole wheat toast with butter and jam.
- B. Oatmeal with butter, artificial sweetener, and strawberries, and 6 ounces of coffee.
- C. Banana pancake with maple syrup, sausage links, half grapefruit, and low-fat milk.
- D. Orange juice, yogurt with berries, cold cereal with milk, bran muffin with margarine.
Correct Answer: B
Rationale: The correct answer is B. Oatmeal with butter, artificial sweetener, and strawberries is a suitable choice for a client with type 2 diabetes mellitus and chronic kidney disease as it provides a balanced meal that helps manage blood sugar levels and kidney function. Choice A contains high saturated fats and added sugars from bacon, butter, and jam, which are not ideal for this client. Choice C includes high sugar content from maple syrup and pancake, which can negatively impact blood sugar levels. Choice D contains high sugar content from orange juice and cold cereal, which can lead to blood sugar spikes, not suitable for a client with diabetes and CKD.
A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme inhibitor (ACEI). Which instruction should the nurse include in the medication teaching plan?
- A. Increase intake of potassium-rich foods
- B. Report increased bruising or bleeding
- C. Stop medication if a cough develops
- D. Limit intake of leafy green vegetables
Correct Answer: B
Rationale: The correct instruction for the nurse to include in the medication teaching plan for a client receiving enalapril, an ACE inhibitor, is to 'Report increased bruising or bleeding.' ACE inhibitors can cause thrombocytopenia, which can lead to an increased risk of bruising and bleeding. Monitoring and reporting these symptoms promptly are essential to prevent complications. Choices A, C, and D are incorrect because increasing potassium-rich foods, stopping medication if a cough develops, and limiting intake of leafy green vegetables are not directly related to the common side effects or actions of ACE inhibitors.
A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Prothrombin time (PT)
- C. Serum sodium level
- D. Hemoglobin level of 12 g/dl
Correct Answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.
Which assessment is most important for the nurse to include in the daily plan of care for a client with a burned extremity?
- A. Distal pulse intensity
- B. Skin integrity
- C. Pain levels
- D. Range of motion
Correct Answer: A
Rationale: The correct answer is A: Distal pulse intensity. Monitoring distal pulses is crucial to ensure that circulation to the extremity is not compromised. This assessment helps in detecting any signs of decreased circulation, which is vital in managing a burned extremity. While skin integrity (choice B), pain levels (choice C), and range of motion (choice D) are also important assessments, monitoring distal pulse intensity takes precedence as it directly reflects the perfusion status of the affected extremity in a burned client.
The nurse is preparing a 50 ml dose of 50% dextrose IV for a client with insulin shock. What is the most immediate intervention by the nurse?
- A. Dilute the dextrose in one liter of 0.9% Normal Saline solution.
- B. Mix the dextrose in a 50 ml piggyback for a total volume of 100 ml.
- C. Push the undiluted dextrose slowly through the current IV infusion.
- D. Ask the pharmacist to add the dextrose to a TPN solution.
Correct Answer: C
Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.
