Which of the following interpretations of this finding should the nurse make?
- A. The presenting part is 1 cm above the ischial spines.
- B. The presenting part is 1 cm below the ischial spines.
- C. The cervix is 1 cm dilated.
- D. The cervix is effaced 1 cm.
Correct Answer: A
Rationale: The finding of "station -1" indicates that the presenting part of the baby is 1 cm above the ischial spines in the mother's pelvis. Station is a measurement used in obstetrics to describe the position of the presenting part of the fetus in relation to the ischial spines of the mother's pelvis during labor. Stations are measured in centimeters and range from -5 (highest) to +5 (lowest). In this case, a station of -1 means the baby's presenting part is 1 cm above the ischial spines. This information helps healthcare providers assess the progress of labor and determine the positioning of the baby during delivery.
A woman's temperature has just risen 0.4°F and will remain elevated during the remainder of her cycle. She expects to menstruate in about 2 weeks. Which of the following hormones is responsible for the change?
- A. Progesterone
- B. Follicle stimulating hormone
- C. Luteinizing hormone
- D. Estrogen
Correct Answer: D
Rationale: The hormone responsible for the increase in body temperature prior to menstruation is estrogen. Estrogen is the primary female sex hormone that plays a key role in regulating the menstrual cycle. Around the time of ovulation, estrogen levels peak, which can lead to a slight rise in body temperature. This increase in temperature is known as the "estrogenic temperature shift" and is a normal part of the menstrual cycle. The rise in body temperature indicates that ovulation has occurred and that a woman is approaching her fertile window. Estrogen also helps prepare the uterine lining for pregnancy and plays a role in many other reproductive functions.
A healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?
- A. HCO3- 30 mEq/L
- B. PaCO2 50 mm Hg
- C. pH 7.45
- D. Potassium 3.3 mEq/L
Correct Answer: B
Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.
The nurse is assessing a pregnant client with hyperemesis gravidarum. What is the priority nursing action?
- A. Monitor for dehydration and electrolyte imbalances.
- B. Encourage the client to eat small, frequent meals.
- C. Provide antiemetic medication as prescribed.
- D. Assess for fetal growth restriction.
Correct Answer: A
Rationale: Monitoring for dehydration and electrolyte imbalances is critical due to the risk of complications from persistent vomiting.
A client with acute respiratory failure (ARF) may present with which of the following manifestations? (Select one that doesn't apply.)
- A. Severe dyspnea
- B. Decreased level of consciousness
- C. Headache
- D. Nausea
Correct Answer: D
Rationale: In acute respiratory failure (ARF), the body is not getting enough oxygen, leading to respiratory distress. Symptoms of ARF typically include severe dyspnea (difficulty breathing), decreased level of consciousness due to hypoxia, and headache from inadequate oxygenation to the brain. Nausea is not a typical manifestation of ARF and would not be expected in this condition.
