Correct Answer: B

Rationale: The correct answer is B. HIPAA guidelines specify that only healthcare professionals directly involved in a patient's care should access their medical information. Asking a nurse from another unit to assist with documentation involves sharing patient information with someone not directly caring for the patient, which violates HIPAA guidelines. Choices A, C, and D involve individuals directly involved in the client's care, making them appropriate actions in line with HIPAA regulations. Choice A involves educating a nursing student under the supervision of the nurse, which is permissible. Choice C involves communicating with the client's designated healthcare decision-maker, which is also allowed under HIPAA. Choice D involves discussing the client's status with another healthcare professional directly involved in the client's care, which is within HIPAA guidelines.

Correct Answer: C

Rationale: Injuries at the level of the 2nd cervical vertebra can affect the phrenic nerve, leading to potential impairment of respiratory function. Assessing respiratory function is crucial as compromised breathing can quickly escalate to life-threatening situations. While response to stimuli is important, ensuring adequate oxygenation takes precedence due to the immediate threat to life. Bladder control may be affected by spinal cord injuries at higher levels, but it is not the priority in this scenario. Muscle strength is a potential consequence of cervical spinal cord injury, but assessing respiratory function is more critical in the acute phase.

Correct Answer: A

Rationale: An ankle-foot orthotic is the correct choice to prevent a plantar flexion contracture in a paralyzed limb. An ankle-foot orthotic helps maintain proper alignment of the foot and ankle, preventing the foot from being permanently fixed in a pointed-down position. Continuous passive motion machines are typically used to promote joint movement after surgery and would not address the prevention of contractures in this case. Abduction splints are used to keep the legs apart and would not address the specific issue described. Sequential compression devices are used to prevent deep vein thrombosis by promoting circulation in the lower extremities and are not indicated for preventing plantar flexion contractures.

Correct Answer: A

Rationale: An oil retention enema containing mineral oil is the most suitable choice to help soften and loosen a fecal impaction before digital removal. Mineral oil lubricates and softens the stool, facilitating passage. Saline enemas draw water into the colon to promote bowel movements but may not effectively soften a fecal impaction. Soapy water enemas are primarily for cleansing, not softening stool. Hypertonic enemas eliminate fluid from the body and are not appropriate for loosening fecal impactions.

Correct Answer: A

Rationale: The correct location to auscultate the pulmonary valve is the second intercostal space at the left sternal border. This area is where the pulmonary valve can best be heard due to its anatomical position. Choice B, the fifth intercostal space at the midclavicular line, is the location for auscultating the mitral valve. Choice C, the fourth intercostal space at the left sternal border, is the area for the tricuspid valve. Choice D, the fifth intercostal space at the left anterior axillary line, is the site for listening to the mitral valve as well. Therefore, option A is the correct choice for auscultating the pulmonary valve.
