The test used to screen for gestational diabetes is the:
- A. Glycosylated hemoglobin test.
- B. Glucose challenge test.
- C. Oral glucose tolerance test.
- D. Postprandial glucose test.
Correct Answer: B
Rationale: The correct answer is B: Glucose challenge test. This test is used to screen for gestational diabetes as it involves drinking a glucose solution and measuring blood sugar levels afterward. This test is specifically designed to assess how well the body processes sugar during pregnancy. The other choices are incorrect because:
A: Glycosylated hemoglobin test measures average blood sugar levels over the past 2-3 months and is not specific for gestational diabetes.
C: Oral glucose tolerance test is used to diagnose gestational diabetes, not to screen for it.
D: Postprandial glucose test measures blood sugar levels after a meal and is not the recommended screening test for gestational diabetes.

Which infant is most likely to express Rh incompatibility?
- A. Infant of an Rh-negative mother and a father who is Rh positive and homozygous for the Rh factor.
- B. Infant who is Rh negative and a mother who is Rh negative.
- C. Infant of an Rh-negative mother and a father who is Rh positive and heterozygous for the Rh factor.
- D. Infant who is Rh positive and a mother who is Rh positive.
Correct Answer: A
Rationale: Rationale:
1. Rh incompatibility occurs when the mother is Rh-negative and the father is Rh-positive.
2. If the father is homozygous for Rh factor (AA), all offspring will be Rh-positive.
3. The Rh-positive offspring from an Rh-negative mother can lead to Rh incompatibility.
4. Therefore, the infant of an Rh-negative mother and a father who is Rh positive and homozygous for the Rh factor is most likely to express Rh incompatibility.
Summary:
- Choice B is incorrect because both mother and infant are Rh-negative.
- Choice C is incorrect because the father being heterozygous for the Rh factor would not result in all offspring being Rh-positive.
- Choice D is incorrect as both mother and infant are Rh-positive, so there is no risk of Rh incompatibility.
The nurse has completed instructions on ways to improve the client’s symptoms related to her rectocele. Which statement by the client indicates a need for further education?
- A. Weight loss will decrease pressure on the pelvic floor.
- B. Increasing fiber and water in my diet will help prevent constipation.
- C. Heavy lifting will not affect my rectocele.
- D. Kegel exercises will help with pelvic floor strength.
Correct Answer: C
Rationale: The correct answer is C because heavy lifting can worsen rectocele symptoms by putting strain on the pelvic floor muscles. A is correct because weight loss reduces pressure. B is correct because fiber and water prevent constipation. D is correct because Kegel exercises strengthen the pelvic floor.
For HIV treatment, the pregnant woman should be expected to receive:
- A. Antibiotics
- B. Protease analogues
- C. Zidovudine
- D. Acyclovir
Correct Answer: C
Rationale: Rationale:
1. Zidovudine (AZT) is recommended for HIV-infected pregnant women to reduce the risk of vertical transmission to the baby.
2. It inhibits viral replication and decreases viral load in the mother, reducing transmission to the fetus.
3. Antibiotics are not effective for HIV treatment. Protease analogues are not typically used in pregnancy due to safety concerns. Acyclovir is used for herpes simplex virus, not HIV.
A nurse is providing preoperative teaching for a woman who is undergoing a total mastectomy. Which will this teaching include? Select all that apply.
- A. Explain that she will have an IV, a drain, and a dressing in place on awakening. Tell her about expectations she may have regarding physical appearance, pain management, equipment that will be used (IVs, drains, etc.).
- B. Explain that she will be provided pain management as needed; monitor and review the pain scale to be used to identify level of intensity.
- C. Have her elevate the affected arm with pillows.
- D. Turn the woman every 4 hours, alternating between the unaffected side and affected side. To prevent pneumonia and complications, have her cough and take deep breaths every 2 hours, while nurse applies support to the chest.
Correct Answer: C
Rationale: Rationale for Answer C (Correct Answer):
1. Elevating the affected arm with pillows post-mastectomy helps reduce swelling and promote lymphatic drainage, aiding in preventing lymphedema.
2. By elevating the arm, it reduces strain on the surgical site and surrounding tissues, promoting comfort and aiding in the healing process.
3. This positioning also helps in preventing postoperative complications such as shoulder stiffness and contractures.
Summary of Why Other Choices are Incorrect:
- Choice A: While important aspects of preoperative teaching, it does not specifically address the need to elevate the affected arm post-mastectomy.
- Choice B: Pain management is crucial, but it does not directly relate to the need for arm elevation post-mastectomy.
- Choice D: Turning every 4 hours and coughing exercises are important for preventing complications but do not address the specific need for arm elevation post-mastectomy.
The nurse taught a class on HPV and cervical cancer. Which statement by the student indicates a need for further teaching?
- A. Most HPV infections resolve on their own within 1 to 2 years.
- B. I can get the HPV vaccination to prevent the most common types of HPV that could cause cervical cancer.
- C. Genital warts cause cervical cancer.
- D. A persistent infection of HPV type 16 or 18 can lead to cervical cancer.
Correct Answer: C
Rationale: The correct answer is C: Genital warts cause cervical cancer.
Rationale:
1. Genital warts are caused by certain types of HPV, not cervical cancer.
2. Most HPV infections do resolve on their own, making choice A correct.
3. HPV vaccination can prevent common types of HPV that cause cervical cancer, supporting choice B.
4. Persistent infection with high-risk HPV types, like 16 or 18, can lead to cervical cancer, aligning with choice D.
Summary:
Option C is incorrect because it inaccurately states that genital warts cause cervical cancer. The other choices are correct in their statements regarding HPV infections, vaccination, and the relationship between specific HPV types and cervical cancer.
