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: Termination in the nurse-client relationship should first be addressed in the orientation phase. This is because the client has a right to know the parameters of the relationship from the beginning. During the orientation phase, it is important to discuss if the relationship is time-limited, inform the client about the number of sessions, or explain that it is open-ended with the termination date to be negotiated later. Addressing termination in the orientation phase helps establish transparency and clear communication. Choices A, B, and D are incorrect because termination discussions should ideally start at the beginning of the relationship to set appropriate expectations.

Correct Answer: D

Rationale: Inhalation injury is the most common cause of injury from a house fire. When a fire occurs, the smoke produced contains harmful gases and particles that can be inhaled, leading to serious respiratory issues. This makes inhalation injury the primary concern during a house fire. Choices A, B, and C are less likely to be the primary cause of injury. While explosions may occur in some cases, inhalation of smoke and toxic fumes is generally the most prevalent danger. Falls from windows and thermal damage to the skin are also significant risks but typically occur after inhalation injuries in the sequence of events during a house fire.

Correct Answer: B

Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.

Correct Answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing symptoms such as pain and difficulty walking. Hallux valgus is commonly known as a bunion and involves the deviation of the big toe towards the other toes. Hammertoe is a condition where one or more toes are bent in a claw-like position. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not typically associated with a mass causing difficulty walking.
