A male newborn is diagnosed with polycystic kidneys which requires autosomal dominant transmission.One of the parents is believed to have this genetic disease.
The nurse's teaching should be based on the fact that with autosomal dominant inheritance:

50% of the offspring have a chance of developing the disease from the affected parent.

Diseases are transmitted from a carrier mother to her son.

All of the offspring will develop the disease.

50% of the offspring will be carriers of the disease from the affected parent.

Answer and Explanation

The Correct Answer is A

Choice A rationale

50% of the offspring have a chance of developing the disease from the affected parent. Autosomal dominant inheritance means that a single copy of the altered gene in each cell is sufficient to cause the disorder. Thus, each child of an affected parent has a 50% chance of inheriting the condition.

Choice B rationale

Diseases transmitted from a carrier mother to her son typically describe X-linked recessive inheritance, not autosomal dominant. In autosomal dominant conditions, both males and females can be affected, and it doesn't depend on the sex of the parent transmitting the gene.

Choice C rationale

All of the offspring will develop the disease is incorrect. In autosomal dominant inheritance, there is a 50% chance of passing the altered gene to the offspring, not 100%.

Choice D rationale

50% of the offspring will be carriers of the disease from the affected parent is incorrect for autosomal dominant inheritance. There are no "carriers" in autosomal dominant diseases; individuals either have the disease or they don't, based on whether they inherit the altered gene.

Correct Answer is D

Explanation

Choice A rationale

Calling the healthcare provider delays immediate intervention needed to alleviate the client's symptoms of dizziness and nausea due to supine hypotensive syndrome. Quick repositioning is crucial to improve venous return and alleviate the symptoms.

Choice B rationale

Elevating the head of the bed will not relieve the pressure on the inferior vena cava caused by the supine position. This intervention does not address the underlying cause of the client's symptoms.

Choice C rationale

Encouraging deep breathing is unlikely to resolve the symptoms of supine hypotensive syndrome, which is caused by the compression of the vena cava by the gravid uterus when lying supine. This intervention does not address the physiological cause.

Choice D rationale

Turning her to her side relieves the pressure on the inferior vena cava, improving venous return and increasing blood pressure. This is the correct initial action to address the symptoms of supine hypotensive syndrome.

A. Avoid foods with strong aromas. B. Eat crackers or plain toast in the morning. C. Drink a glass of orange juice before getting out of bed. D. Eat a high carbohydrate snack before going to sleep.

Correct Answer is C

Explanation

Choice A rationale

Avoiding foods with strong aromas can help reduce nausea, as certain smells can trigger the sensation. This strategy is usually effective because olfactory stimuli can have a significant impact on nausea and vomiting during pregnancy.

Choice B rationale

Eating crackers or plain toast in the morning can help manage nausea by stabilizing blood sugar levels before getting out of bed. This simple carbohydrate source can provide quick energy and prevent morning sickness.

Choice C rationale

Drinking a glass of orange juice before getting out of bed is not recommended, as the acidity of the juice can irritate the stomach lining and exacerbate nausea. It is better to have bland, non-acidic foods first.

Choice D rationale

Eating a high-carbohydrate snack before going to sleep can help maintain stable blood sugar levels overnight, potentially reducing morning nausea. Carbohydrates are effective in providing sustained energy and preventing dips in glucose that can trigger nausea.
