When caring for a laboring client whose contractions are occurring every 2-3 minutes, the nurse should document that the pump is infusing how many ml/hour?
- A. 5
- B. 10
- C. 15
- D. 20
Correct Answer: A
Rationale: The correct answer is A: 5 ml/hour. To calculate the infusion rate, you need to divide the total amount infused by the total time in hours. Given contractions every 2-3 minutes, which is equivalent to 20-30 contractions per hour, the pump should infuse at 5 ml/hour to ensure proper medication delivery. Choices B, C, and D are incorrect because they do not correspond to the frequency of contractions and may lead to under or overmedication.

A client with type 2 diabetes mellitus is admitted for antibiotic treatment of a leg ulcer. Which signs and symptoms, indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), should the nurse report to the healthcare provider? (Select one that doesn't apply.)
- A. Increased heart rate
- B. Visual disturbances
- C. Presence of uremic frost
- D. Decreased mentation
Correct Answer: C
Rationale: The correct answer is C: Presence of uremic frost. HHNS is characterized by severe hyperglycemia leading to osmotic diuresis and dehydration, not uremia. A: Increased heart rate is a non-specific sign of stress. B: Visual disturbances can be seen in diabetic retinopathy but are not specific to HHNS. D: Decreased mentation is common in HHNS due to severe dehydration and hyperglycemia leading to altered mental status.
The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: C
Rationale: Rationale:
1. Heparin primarily affects the intrinsic pathway of coagulation.
2. International Normalized Ratio (INR) is used to monitor the effectiveness of anticoagulation therapy.
3. INR is more specific for monitoring heparin therapy compared to other options.
4. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) are not as accurate for heparin monitoring.
5. Partial Thromboplastin Time (PTT) is used to monitor heparin therapy, but INR is a more precise indicator of heparin's effect.
A client who has had three spontaneous abortions is requesting information about possible causes. The nurse's response should be based on which information?
- A. Chromosomal abnormalities are the most common cause of early spontaneous abortions
- B. Incompetent cervix can cause spontaneous abortions
- C. An infection can cause spontaneous abortions
- D. Nutritional deficiencies are the most common cause of early spontaneous abortions
Correct Answer: A
Rationale: The correct answer is A because chromosomal abnormalities are indeed the most common cause of early spontaneous abortions. These abnormalities can occur during fertilization or early cell division, leading to non-viable embryos. Choice B, incompetent cervix, typically causes late-term miscarriages. Choice C, infections, can contribute to miscarriages but are not the most common cause. Choice D, nutritional deficiencies, can impact pregnancy outcomes but are not the primary cause of early spontaneous abortions. In summary, the correct answer A is supported by the fact that chromosomal abnormalities are the leading cause of early spontaneous abortions, while the other choices are either more relevant to late-term miscarriages or less commonly associated with early pregnancy loss.
A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct Answer: C
Rationale: Step 1: Elevated urine specific gravity indicates increased concentration of urine, a sign of dehydration.
Step 2: In dehydration, the body conserves water, leading to concentrated urine.
Step 3: The child's symptoms (increased stools, liquid consistency, fever, vomiting) suggest dehydration.
Step 4: Other choices (A: occult blood, B: distention, D: hyperactive bowel sounds) are not specific to dehydration.
Summary: Elevated urine specific gravity is key as it directly reflects dehydration, unlike the other choices which are not specific indicators of dehydration.
A 9-year-old received a short arm cast for a right radius. To relieve itching under the child's cast, which instructions should the nurse provide to the parents?
- A. Blow cool air from a hair dryer under the cast
- B. Twist the cast back and forth
- C. Shake powder into the cast
- D. Push a pencil under the cast edge
Correct Answer: A
Rationale: The correct answer is A: Blow cool air from a hair dryer under the cast. This method helps to relieve itching by providing airflow without causing damage to the cast or skin. It is safe and effective.
Choice B: Twisting the cast back and forth may cause discomfort or injury to the child's arm.
Choice C: Shaking powder into the cast can create a mess and may lead to skin irritation or infection.
Choice D: Pushing a pencil under the cast edge can cause damage to the skin or lead to complications.
