1. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
2. Why is a primigravida instructed to offer her breast to the baby for the first time within 30 minutes after delivery?
- A. To initiate the occurrence of milk letdown
- B. To stimulate milk production by the mammary acini
- C. To provide the baby with colostrum
- D. To allow the mother to practice breastfeeding in the presence of healthcare providers
Correct answer: C
Rationale: Offering the breast to the baby early after delivery ensures that the baby receives colostrum, the initial milk produced by the mammary glands rich in antibodies and essential nutrients, which are crucial for the newborn's health and immune system. This early breastfeeding also helps establish the mother-infant bond and promotes successful breastfeeding in the long term.
3. A nurse is teaching a client who is to undergo total knee arthroplasty about postoperative care. Which of the following instructions should the nurse include?
- A. Apply heat to the affected knee
- B. Avoid placing pillows under the knee
- C. Avoid moving the knee for 2-3 days
- D. Apply ice to the affected knee for 24-48 hours
Correct answer: D
Rationale: The correct answer is to apply ice to the affected knee for 24-48 hours. Applying ice helps to reduce inflammation and pain after knee surgery, promoting healing. Choice A is incorrect because heat is not recommended postoperatively, as it can increase swelling. Choice B is incorrect because pillows should be placed under the knee to keep it elevated. Choice C is incorrect because early mobilization is essential for preventing complications such as blood clots.
4. Nutrients interact in the body to regulate metabolic processes, build and repair tissue, and to:
- A. provide energy.
- B. control cellular wastes.
- C. control hormone levels.
- D. regulate absorption.
Correct answer: A
Rationale: The correct answer is A: provide energy. Nutrients play a crucial role in providing energy for the body's various functions. While they do help in regulating metabolic processes and in building and repairing tissue, the primary function related to energy production. Choices B, C, and D are incorrect as nutrients are not primarily responsible for controlling cellular wastes, hormone levels, or absorption.
5. A nurse is preparing a change-of-shift report for an adult female client who is postoperative. Which of the following client information should the nurse include in the report?
- A. Hgb 12.8 g/dl.
- B. Potassium 4.2 mEq/L.
- C. RBC 4.4 million/mm3.
- D. Platelets 100,000/mm3.
Correct answer: D
Rationale: The correct answer is D: "Platelets 100,000/mm3." A platelet count of 100,000/mm3 is low and increases the client's risk for bleeding, which is crucial information to communicate during the change-of-shift report. Choices A, B, and C provide values within normal ranges and are not directly related to the client's postoperative status or risk for complications. Therefore, they are not the priority information to include in the report.
