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 3-year-old pediatric patient's mother would like to stay at the patient's bedside throughout the night as the patient seems calmer when she is present. What is the most caring and appropriate response?

A. Reinforce visiting hours
B. Allow her to stay for a short period beyond normal hours
C. Allow her to stay throughout the night
D. Offer to get bedding for a couch in the waiting room

Correct answer: C

Rationale: Allowing the mother to stay throughout the night is the most caring and appropriate response in this situation. Pediatric facilities often recognize the crucial role parents play in their child's care and are supportive of unlimited visitation. Allowing the mother to stay can help maintain the child's calmness and enhance the bond between the family and healthcare team. Reinforcing visiting hours (Choice A) may not address the specific needs of this situation where the child benefits from the mother's presence. Allowing her to stay for a short period beyond normal hours (Choice B) may not fully address the need for her continuous presence. Offering to get bedding for a couch in the waiting room (Choice D) may not be necessary if the mother can stay with her child in the patient's room.

3. What is the highest priority for post ECT care?

A. Observe for confusion
B. Monitor respiratory status
C. Reorient to time, place, and person
D. Document the client's response to the treatment

Correct answer: B

Rationale: The highest priority for post ECT care is to monitor respiratory status. This is crucial because a life-threatening side effect of ECT is respiratory arrest. While observing for confusion and reorienting the client are important aspects of post ECT care, they are not as critical as ensuring the client's respiratory status is stable. Documenting the client's response to treatment is also important for maintaining accurate medical records, but it is not the highest priority immediately post ECT.

4. Which action represents the evaluation stage of the plan of care?

A. The nurse assigns a nursing diagnosis of Impaired Skin Integrity related to diminished skin circulation
B. The nurse assesses the client's vital signs and asks about symptoms
C. The nurse determines that the client is not meeting his set outcomes and makes revisions
D. The nurse discusses the client's health history

Correct answer: C

Rationale: The correct answer is C. The evaluation stage of the nursing process involves reviewing the assessments, diagnoses, and interventions given to the client and then determining if the client is meeting expected outcomes. In this scenario, the nurse is assessing whether the client is meeting the outcomes set for their care plan and making revisions as needed. Choice A is incorrect as assigning a nursing diagnosis is part of the nursing diagnosis phase, not the evaluation phase. Choice B represents the assessment phase of the nursing process, not the evaluation phase. Choice D involves discussing the client's health history, which is more aligned with the assessment phase rather than the evaluation phase.

5. What preparation is necessary for a colposcopy procedure?

A. NPO for 8-12 hours before the procedure.
B. D/C all hypertension medications for two days prior to the procedure.
C. Take three Dulcolax tablets and two containers of Miralax the day before to clear out the lower GI system.
D. None of the above prep is necessary for this type of procedure.

Correct answer: D

Rationale: A colposcopy procedure is performed to examine the vagina and cervix. The only preparation required is washing the external genitals with soap and water on the morning of the procedure. Choices A, B, and C suggest unnecessary preparations that are not relevant to a colposcopy. NPO for 8-12 hours, discontinuing hypertension medications, and using laxatives are not part of the standard preparation for a colposcopy.
