Correct Answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

Correct Answer: A

Rationale: In an emergency situation to assess for airway obstruction, the nurse should prioritize assessing the client's ability to speak. If a client can speak, it indicates that the airway is patent and not completely obstructed, allowing air to pass through the vocal cords for speech production. Choices B, C, and D are not the primary assessments for determining airway obstruction. Assessing the ability to hear is not directly related to an airway obstruction. While oxygen saturation and adventitious breath sounds are important in respiratory assessments, they are not the initial indicators of an airway obstruction. Oxygen saturation reflects the amount of oxygen in the blood, and adventitious breath sounds refer to abnormal lung sounds that may indicate conditions like pneumonia or bronchitis, but they do not specifically confirm airway patency.

Correct Answer: A

Rationale: Padding on a restraint helps distribute pressure to prevent bony prominences from bearing excessive pressure when a client pulls against the restraints. This is crucial to avoid tissue damage caused by ischemia. The correct answer focuses on the physiological benefit of padding in reducing pressure on vulnerable areas to prevent harm. Choice B is incorrect as the primary purpose of padding is not emotional comfort but preventing physical harm. Choice C is incorrect as while padding can indirectly help prevent infection and wounds by reducing pressure, its primary function is pressure distribution. Choice D is incorrect as the main purpose of padding is not to keep the restraints in place but to protect the client's skin and tissues from pressure-related injuries.

Correct Answer: D

Rationale: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.

Correct Answer: C

Rationale: The correct answer is, "What can I do to assist you to care for him at home?"? This response shows cultural sensitivity and respect for the family's values. In many Asian cultures, there is a strong tradition of caring for elders at home rather than in a long-term care facility. By offering assistance to the family in caring for their elderly member at home, the nurse shows understanding and support. Choices A, B, and D are incorrect because they do not acknowledge or respect the family's cultural beliefs and values regarding caring for elderly family members.
