1. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?
- A. 16 ml/hour.
- B. 18 ml/hour.
- C. 20 ml/hour.
- D. 22 ml/hour.
Correct answer: C
Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.
2. The nurse is caring for a child who has been diagnosed with attention deficit hyperactivity disorder (ADHD). What is the most important intervention for the nurse?
- A. Help the child enroll in a special education class.
- B. Allay any feelings of guilt the parents may have.
- C. Explain to the parents that medications are lifelong.
- D. Teach the parents how to set limits.
Correct answer: B
Rationale: The most important intervention for the nurse in caring for a child with ADHD is to allay any feelings of guilt the parents may have. Parents of children with ADHD often experience guilt or self-blame, thinking they are responsible for their child's condition. By addressing and alleviating these feelings, the nurse can support the parents in a crucial way. Choice A is not the most important intervention because enrolling the child in a special education class might be a consideration but does not address the emotional needs of the parents. Choice C is incorrect because stating that medications are lifelong may cause unnecessary distress to the parents. Choice D is also not the most important intervention as setting limits is important but not as critical as addressing parental guilt and emotions.
3. A client with liver cirrhosis is at risk for developing hepatic encephalopathy. Which clinical manifestation should the nurse monitor for?
- A. Kussmaul respirations
- B. Asterixis (flapping tremor)
- C. Bradycardia
- D. Hypertension
Correct answer: B
Rationale: Corrected Rationale: Asterixis, also known as a flapping tremor, is a common sign of hepatic encephalopathy, indicating neurological dysfunction due to liver failure. Kussmaul respirations (option A) are associated with metabolic acidosis, which is not a typical manifestation of hepatic encephalopathy. Bradycardia (option C) and hypertension (option D) are not typically associated with hepatic encephalopathy; in fact, hepatic encephalopathy is more commonly associated with alterations in mental status, neuromuscular abnormalities, and changes in behavior.
4. A client with Cushing's Syndrome is recovering from an elective laparoscopic procedure. Which assessment finding warrants immediate intervention by the nurse?
- A. Irregular apical pulse
- B. Purple marks on the skin of the abdomen
- C. Quarter-sized blood spot on the dressing
- D. Pitting ankle edema
Correct answer: A
Rationale: The correct answer is A: Irregular apical pulse. In a client recovering from a laparoscopic procedure with Cushing's Syndrome, an irregular apical pulse can be indicative of a life-threatening arrhythmia and requires immediate intervention. Choices B, C, and D are not as urgent as an irregular apical pulse. Purple marks on the skin of the abdomen may be related to Cushing's Syndrome, a quarter-sized blood spot on the dressing can be managed with appropriate wound care, and pitting ankle edema may be expected postoperatively but does not require immediate intervention.
5. The nurse is teaching a client how to collect a sputum specimen. Which steps should the nurse instruct the client to follow when collecting sputum?
- A. Breathe deeply, followed by swallowing.
- B. Breathe deeply, followed by spitting into a cup.
- C. Breathe deeply, followed by coughing up the sputum.
- D. Breathe deeply, followed by clearing the throat.
Correct answer: C
Rationale: The correct answer is to instruct the client to breathe deeply followed by coughing up the sputum. This method ensures that the specimen is collected from the lower respiratory tract and is not contaminated by saliva. Choice A (swallowing) does not result in sputum collection, while choice B (spitting into a cup) may lead to saliva contamination. Choice D (clearing the throat) is not an effective way to collect sputum as it may involve getting rid of saliva, not sputum.
