Nursing Elites

1. A child has recently been diagnosed with Duchenne muscular dystrophy (DMD). The parents are receiving genetic counseling prior to planning another pregnancy. Which of the following statements includes the most accurate information?

• A. Duchenne is an X-linked recessive disorder, so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.
• B. Duchenne is an X-linked recessive disorder, so both daughters and sons have a 50% chance of developing the disease.
• C. Each child has a 1 in 4 (25%) chance of developing the disorder.
• D. Sons only have a 1 in 4 (25%) chance of developing the disorder.

Correct answer: A

Rationale: The correct answer is that Duchenne is an X-linked recessive disorder, meaning the affected gene is located on one of the two X chromosomes of a female carrier. If a son receives the X chromosome bearing the gene, he will develop the disease, giving him a 50% chance of being affected. Daughters, on the other hand, are not affected by Duchenne but have a 50% chance of being carriers since they inherit one copy of the defective gene from the mother. The other X chromosome is inherited from the father, who cannot be a carrier. Therefore, choice A is accurate. Choice B is incorrect because daughters do not develop the disease, and sons have a 50% chance of developing, not both having a 50% chance. Choice C is incorrect as it does not consider the X-linked inheritance pattern of Duchenne. Choice D is inaccurate as it incorrectly states that only sons have a 25% chance of developing the disorder, omitting the carrier status of daughters.

2. A physician has written an order for '2.0 mg MS q 2-4 hr prn pain.' What is the nurse's appropriate response to this order?

• A. Give 2 mg of morphine sulfate to the client
• B. Give 20 mg of morphine sulfate to the client
• C. Contact the pharmacy to clarify the order
• D. Contact the physician to rewrite the order

Correct answer: D

Rationale: The physician's order contains several errors that could lead to potential harm to the client if not addressed. The use of '2.0' involves a trailing decimal point, which may lead to confusion regarding the intended dose of the drug. Additionally, the abbreviation 'MS' is considered a Do Not Use abbreviation by the Joint Commission, as it could refer to morphine sulfate or magnesium sulfate, leading to medication errors. While the order indicates the drug should be used for pain, the nurse should contact the physician to clarify the exact dose and specific drug to be administered, ensuring safe and accurate medication administration. Therefore, the correct response is to contact the physician to rewrite the order.

3. Which of the following interventions should be prioritized in the care of the suicidal client?

• A. Remove all potentially harmful items from the client's room
• B. Allow the client to express feelings of hopelessness
• C. Note the client's capabilities to increase self esteem
• D. Set a "no suicide"? contract with the client

Correct answer: A

Rationale: accessibility of the means of suicide increases the lethality. Allowing a patient to express feelings and setting a no suicide contract are interventions for suicidal client but blocking the means of suicide is priority. Increasing self esteem is an intervention for depressed clients but not specifically for suicide.

4. The client is receiving discharge teaching seven (7) days post myocardial infarction and inquires why he must wait six (6) weeks before engaging in sexual intercourse. What is the best response by the nurse to this question?

• A. "You need to regain your strength before attempting such exertion."?
• B. "When you can climb 2 flights of stairs without problems, it is generally safe."?
• C. "Have a glass of wine to relax you, then you can try to have sex."?
• D. "If you can maintain an active walking program, you will have less risk."?

Correct answer: B

Rationale: Following a myocardial infarction, there is a risk of cardiac rupture at the site of the infarction for approximately six (6) weeks until scar tissue forms. The advice to wait until the client can climb two flights of stairs without issues is common among healthcare providers as it indicates an adequate level of physical exertion tolerance and suggests a lower risk of complications during sexual activity. Choice A is not specific to the recovery timeline related to sexual activity post-myocardial infarction. Choice C is inappropriate as alcohol consumption should not be recommended before sexual activity. Choice D, though promoting an active lifestyle, does not directly address the safety concerns related to sexual intercourse post-myocardial infarction.

5. Sinusitis is caused by:

• A. Bacteria
• B. Fungus
• C. Virus
• D. Any of the above

Correct answer: D

Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.
