Nursing Elites

1. An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?

• A. Torticollis, with shortening of the sternocleidomastoid muscle
• B. Craniosynostosis, with premature closure of the cranial sutures
• C. Plagiocephaly, with flattening of one side of the head
• D. Hydrocephalus, with increased head size

Correct answer: A

Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.

2. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?

• A. Peaked T waves on the ECG
• B. Muscle spasms
• C. Constipation
• D. A prominent U wave on the ECG

Correct answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

3. 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.

4. Tommy R., your 68-year-old patient, is at risk for falls. He has fallen 3 times in the last month. You should keep Tommy's ______________ in order to prevent him from falling again.

• A. bedside rails up at all times
• B. bed in the low position
• C. call bell within reach
• D. family members in the room at all times

Correct answer: C

Rationale: To prevent falls, it is essential to keep the patient's call bell within reach so they can easily call for help when needed. This allows for timely assistance and can prevent falls. While low beds can reduce the severity of injuries in case of a fall, they do not prevent falls from happening. Having family members in the room at all times is not a realistic or practical solution. Side rails can actually increase the severity of falls as patients may attempt to climb over them, and using side rails as fall prevention is considered a restraint practice that can lead to entrapment and other risks.

5. A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?

• A. Walk barefoot whenever possible.
• B. Use a heating pad to keep feet warm.
• C. Avoid crossing the legs.
• D. Use antibacterial ointment to treat skin lesions prone to infection.

Correct answer: C

Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.
