1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
2. A client with deep vein thrombosis (DVT) in the left leg is on a heparin protocol. Which intervention is most important for the nurse to include in this client's plan of care?
- A. Observe for bleeding side effects related to heparin therapy.
- B. Assess blood pressure and heart rate at least every 4 hours.
- C. Measure calf girth to evaluate edema in the affected leg.
- D. Encourage mobilization to prevent pulmonary embolism.
Correct answer: A
Rationale: The correct answer is to 'Observe for bleeding side effects related to heparin therapy.' This is the most crucial intervention for a client with deep vein thrombosis (DVT) on a heparin protocol. Heparin, being an anticoagulant, increases the risk of bleeding as a side effect. Therefore, close monitoring for signs of bleeding, such as bruising, petechiae, or blood in stool or urine, is essential to prevent severe complications. While assessing blood pressure and heart rate (Choice B) is important, it is not as critical as monitoring for bleeding. Measuring calf girth (Choice C) may help evaluate edema but is not as vital as observing for bleeding complications. Encouraging mobilization (Choice D) is beneficial for preventing complications like pulmonary embolism, but in this scenario, monitoring for bleeding takes precedence due to the immediate risk associated with anticoagulant therapy.
3. The nurse is preparing to administer an oral antibiotic to a client with unilateral weakness, ptosis, mouth drooping, and aspiration pneumonia. What is the priority nursing assessment that should be done before administering this medication?
- A. Ask the client about soft food preferences
- B. Auscultate the client’s breath sounds
- C. Obtain and record the client’s vital signs
- D. Determine which side of the body is weak
Correct answer: B
Rationale: The correct answer is to auscultate the client’s breath sounds. Assessing breath sounds is crucial in this scenario as it helps ensure that the client can safely swallow the oral antibiotic without aspirating. Unilateral weakness, ptosis, mouth drooping, and aspiration pneumonia indicate potential swallowing difficulties, making it essential to assess breath sounds for any signs of respiratory issues. Asking about food preferences (choice A) may be relevant later but is not the priority before administering the medication. While obtaining vital signs (choice C) is important, assessing breath sounds takes precedence in this case. Determining which side of the body is weak (choice D) is not the priority assessment before administering the oral antibiotic.
4. What is the primary focus of postoperative nursing care for the client with colon trauma?
- A. Monitoring for elevated coagulation studies
- B. Observation for and prevention of fistulas
- C. Monitoring for signs of hyponatremia
- D. Observation for and prevention of infection
Correct answer: D
Rationale: The correct answer is D: Observation for and prevention of infection. Postoperative nursing care for a client with colon trauma primarily focuses on preventing infections. Clients with colon trauma are at high risk for infections due to the disruption of the intestinal barrier. Monitoring for signs of infection, maintaining proper wound care, administering antibiotics as prescribed, and implementing strict aseptic techniques are essential in preventing postoperative infections. Choices A, B, and C are incorrect because elevated coagulation studies, fistulas, and hyponatremia are not the primary concerns in the immediate postoperative period for a client with colon trauma.
5. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client? (Enter numeric value only)
- A. 2
- B. 3
- C. 4
- D. 5
Correct answer: A
Rationale: To calculate the maximum dosage in mg that the nurse should administer, multiply the dose per administration (0.4 mg) by the maximum number of doses allowed (5 doses): 0.4 mg/dose * 5 doses = 2 mg. Therefore, the nurse should administer a maximum dosage of 2 mg to the client. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
