A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?
- A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
- B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
- C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
- D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
Correct Answer: A
Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.

The nurse is teaching a client about signs of preterm labor. Which symptom should be reported immediately?
- A. Increased fetal movements.
- B. Lower back pain and cramping.
- C. Mild swelling of the feet.
- D. Occasional Braxton Hicks contractions.
Correct Answer: B
Rationale: Lower back pain and cramping may indicate preterm labor and should be reported promptly.
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.
Before giving a client oral combination contraceptives, which side effects should the nurse tell the patient to be aware of? Select one that does not apply.
- A. Irregular bleeding
- B. Thick vaginal discharge
- C. Nausea
- D. Breast tenderness
Correct Answer: B
Rationale: The common side effects of oral combination contraceptives include irregular bleeding, nausea, and breast tenderness. Choice B is incorrect because thick vaginal discharge is not a typical side effect of oral contraceptives.
The APGAR is performed at what minutes?
- A. 1 and 5
- B. 2 and 4
- C. 5 and 10
- D. At birth and 5 minutes
Correct Answer: A
Rationale: The APGAR score is a quick assessment tool used to evaluate a newborn's health and overall condition immediately after birth and again at 5 minutes after birth. The five categories evaluated in the APGAR score are Appearance, Pulse, Grimace, Activity, and Respiration. The assessment is typically done at 1 minute and 5 minutes after birth to quickly determine if the baby needs any immediate medical attention or interventions. The scores at both time points provide valuable information about the baby's well-being and can guide healthcare providers in deciding on appropriate next steps for care.
On examination the hands and feet of a 6 hours old infant is cyanotic without signs of distress. The nurse should document these findings as:
- A. Potential for respiratory distress
- B. Poor oxygenation
- C. Cold stress
- D. Acrocyanosis
Correct Answer: D
Rationale: Acrocyanosis is a condition commonly seen in newborns where the hands and feet appear blue or purple in color due to decreased circulation in the peripheral blood vessels. It is usually a normal finding in newborns and is not associated with distress or poor oxygenation. Unlike central cyanosis which indicates a more serious underlying issue affecting oxygen levels in the blood, acrocyanosis is a benign and self-limiting condition. It is important for the nurse to recognize and document acrocyanosis to differentiate it from other potentially concerning conditions.
