Question 1

A nurse counsels a couple on sex-linked disorders. Both the man and the woman are carriers of the disorder. They ask the nurse how this disorder will affect any children they might have. The nurse's best response is:

Accepted Answer

The answer of A nurse counsels a couple on sex-linked...

Question 2

The couple has had an ultrasound at 19 weeks' gestation, and their fetus was found to have anencephaly. The nurse is completing counseling for the couple on the ultrasound findings. Which statement indicates that additional teaching is needed?

Accepted Answer

Anencephaly is a neural tube defect and is not related to chromosomal abnormalities. Therefore, waiting for chromosome testing is not necessary or relevant in this situation. The parents need to be educated that anencephaly is caused by incomplete brain development in the fetus and is not linked to their age or genetics.

Question 3

A woman who has had multiple miscarriages is advised to go through genetic testing. The patient asks the nurse the rationale for this recommendation. The nurse will explain that:

Accepted Answer

Genetic defects are a common cause of miscarriages. Testing can help identify any potential genetic issues and inform the woman's healthcare provider about any possible interventions or treatments. The other options are not correct as they do not accurately explain the rationale for genetic testing in this scenario.

Question 4

The clinic nurse is teaching a patient about how to take the basal body temperature (BBT). Place the steps in the order that the nurse provides to the patient. Standard Text: Click and drag the options below to move them up or down. 
A) Choose one site for taking the temperature. 
B) Use the chosen site consistently. 
C) Take the temperature before arising. 
D) Immediately record the temperature. 
E) Shake down the thermometer.

Accepted Answer

The answer of The clinic nurse is teaching a patient...

Question 5

The nurse in the OB-GYN clinic counsels a couple that in autosomal dominant inheritance, which of the following occur?

Accepted Answer

In autosomal dominant inheritance, an affected individual often has an affected parent (A), males and females are equally affected (C), and a father can pass the defective gene to a son (D). The chance of passing on the abnormality is 50%, not 75%, and there can be variances in expression and penetrance.

Question 6

A couple is at the clinic for preconceptual counseling. Both parents are 40 years old. The nurse knows that the education session has been successful when the wife states:

Accepted Answer

At age 40, the risk of having a child with genetic defects, including Down syndrome, increases. Genetic testing can be done early in pregnancy to detect such defects.

Question 7

The clinic nurse assesses a newborn who is not progressing as expected. Genetic tests are ordered. The nurse explains to the parents that the laboratory tests to be done include:

Accepted Answer

The answer of The clinic nurse assesses a newborn who...

Question 8

A patient has been diagnosed with fallopian tube obstruction and told that her best option for becoming pregnant is with in vitro fertilization. The patient asks the nurse about the procedure. The best explanation by the nurse is:

Accepted Answer

In vitro fertilization (IVF) often involves the creation of multiple embryos to increase the chances of pregnancy. Any extra embryos can indeed be cryopreserved for future use if the couple wishes to attempt to conceive again. This option provides flexibility and can save time and resources in future fertility treatments.

Question 9

A pregnant patient asks the nurse, "What is this 'knuckle test' that is supposed to tell whether my baby has a genetic problem?" The nurse correctly explains that:

Accepted Answer

The "knuckle test" is actually called the nuchal translucency test, which measures the thickness of the back of the baby's neck during an ultrasound. This test can help detect Down syndrome and other chromosomal abnormalities. The nurse correctly explains this to the patient.

Question 10

A newborn has been diagnosed with a disorder that occurs through an autosomal recessive inheritance pattern. The parents ask the nurse, "Which of us passed on the gene that caused the disorder?" The nurse tells them it was:

Accepted Answer

In an autosomal recessive inheritance pattern, both parents must carry one copy of the mutated gene and pass it on to their child for the child to express the disorder. Each parent is typically an asymptomatic carrier, meaning they do not show symptoms of the disorder themselves.

Question 11

The couple at 12 weeks' gestation has been told that their fetus has sickle-cell disease. Which statement by the couple indicates that they are adequately coping?

Accepted Answer

Option D indicates that the couple has understood the genetic basis of sickle-cell disease and the likelihood of their child inheriting it. This shows that they are coping well with the news and are informed about the condition. The other options indicate blame, regret, or misinformation, which suggest inadequate coping mechanisms.

Question 12

A nurse working with couples undergoing genetic testing recognizes which of the following as nursing responsibilities?

Accepted Answer

The answer of A nurse working with couples undergoing genetic...

Question 13

A 58-year-old father and a 45-year-old mother gave birth to a baby boy 2 days ago. The nurse assesses a single palmar crease and low-set ears on the newborn. The nurse plans to counsel the couple about which chromosomal abnormality?

Accepted Answer

A single palmar crease and low-set ears are common physical features in newborns with Down syndrome, which is caused by trisomy 21. Trisomy 13 (option A) and trisomy 18 (option B) can present with more severe abnormalities, while trisomy 26 (option D) is not a recognized chromosomal abnormality.

Question 14

The nurse is reviewing preconception questionnaires in charts. Which couple are the most likely candidates for preconceptual genetic counseling?

Accepted Answer

A family history of a genetic disorder, such as hemophilia, is an indication for preconceptual genetic counseling.
