Nokea
The client is admitted to the intensive care unit following a coronary artery bypass graft. The nurse checks the vital signs and notes a heart rate of 120 beats per minute, blood pressure of 70/40, and respiration of 32 breaths per minute. The nurse suspects hypovolemic shock. Which assessment tools would contribute to a diagnosis of hypovolemic shock?
- A. Hemoglobin of 5 g
- B. Central venous pressure of 2 mm of mercury
- C. Pulmonary artery wedge pressure of 16 mm of mercury
- D. Hematocrit of 22%
- E. Troponin (T 1) level of 4 mcg/L
Correct Answer: A, B, D
Rationale: Hypovolemic shock involves low blood volume, reflected by low hemoglobin (5 g, A), low central venous pressure (2 mmHg, B), and low hematocrit (22%, D). Normal pulmonary artery wedge pressure (16 mmHg, C) suggests no left heart failure. Elevated troponin (E) indicates myocardial damage, not volume status.

A client in labor admits to using alcohol throughout the pregnancy. The most recent use was the day before. Based on the client's history, the nurse should give priority to assessing the newborn for:
- A. Respiratory depression
- B. Wide-set eyes
- C. Jitteriness
- D. Low-set ears
Correct Answer: C
Rationale: Fetal alcohol exposure, especially recent use, can cause neonatal withdrawal symptoms like jitteriness. Respiratory depression is less common, and physical anomalies like wide-set eyes or low-set ears are associated with chronic exposure.
The nurse caring for a client with a closed head injury obtains an intracranial pressure (ICP) reading of 17 mmHg. The nurse recognizes that:
- A. The ICP is elevated and the doctor should be notified.
- B. The ICP is normal; therefore, no further action is needed.
- C. The ICP is low and the client needs additional IV fluids.
- D. The ICP reading is not as reliable as the Glasgow coma scale.
Correct Answer: A
Rationale: Normal ICP is 5-15 mmHg. A reading of 17 mmHg is elevated, indicating potential brain swelling, and requires immediate notification of the physician. The Glasgow scale complements but does not replace ICP monitoring.
A 4 year old has an imaginary playmate, which concerns the mother. The nurse's best response would be:
- A. I understand your concern and will assist you with a referral.'
- B. Try not to worry because you will just upset your child.'
- C. Just ignore the behavior and it should disappear by age 8.'
- D. This is appropriate behavior for a preschooler and should not be a concern.'
Correct Answer: D
Rationale: This is normal for a preschooler, and a referral is not appropriate. Telling a parent not to worry is unhelpful. This response does not address the mother's concern. This response is incorrect. The behavior is normal and will usually disappear by the time the child enters school. This behavior is normal development for a preschooler.
The nurse is caring for a client with a diagnosis of hyperemesis gravidarum. Which laboratory finding is most likely to be present?
- A. Metabolic alkalosis
- B. Hyponatremia
- C. Hypokalemia
- D. All of the above
Correct Answer: D
Rationale: Hyperemesis gravidarum causes prolonged vomiting leading to metabolic alkalosis (loss of stomach acid) hyponatremia (electrolyte loss) and hypokalemia (potassium loss). All are likely findings in severe cases.
The nurse would assess the client's correct understanding of the fertility awareness methods that enhance conception, if the client stated that:
- A. My sexual partner and I should have intercourse when my cervical mucosa is thick and cloudy.'
- B. At ovulation, my basal body temperature should rise about 0.5F.'
- C. I should douche immediately after intercourse.'
- D. My sexual partner and I should have sexual intercourse on day 14 of my cycle regardless of the length of the cycle.'
Correct Answer: B
Rationale: A slight rise in basal body temperature (about 0.5°F) after ovulation, due to progesterone, indicates correct understanding of fertility awareness.
