Correct Answer: B

Rationale: The correct answer is B. To examine stiffness and rigidity of the neck, the nurse should move the client's head and chin toward the chest. This maneuver assesses for resistance and limitation in neck flexion, which can indicate stiffness and rigidity commonly seen in neurologic disorders like meningitis or cervical dystonia. A: Positioning the client flat on the bed for hours does not specifically target neck stiffness and rigidity. C: Asking the client to bend and pick up objects assesses motor function, not neck stiffness. D: Introducing a painful stimulus is not a standard or appropriate method for examining neck stiffness and rigidity.

Correct Answer: D

Rationale: The correct answer is D because pupil size is not typically a part of a routine neurological examination. A: Eye movements are assessed to evaluate cranial nerve functions. B: Reflexes help determine the integrity of the spinal cord and peripheral nervous system. C: Nuchal rigidity is important to assess for signs of meningitis or other neurological conditions. In contrast, pupil size is more relevant in ophthalmological examinations or when assessing response to specific medications affecting the pupil size.

Correct Answer: D

Rationale: The correct answer is D: Strengthens heart contraction. Digoxin is an inotropic agent that works by increasing the force of the heart's contractions. This leads to improved cardiac output and helps manage conditions like heart failure. Choices A, B, and C are incorrect because digoxin does not decrease heart rate, increase conduction time, or increase heart rate. It specifically targets the strength of the heart's contractions, making option D the most appropriate choice. This action of digoxin is crucial in improving the efficiency of the heart's pumping function.

Correct Answer: C

Rationale: The correct answer is C. In hypothyroidism, the thyroid gland is underactive, leading to symptoms like puffiness of the face and hands due to fluid retention. This occurs as a result of decreased metabolism. Options A and B are symptoms of hyperthyroidism, where the thyroid gland is overactive. Option D is a symptom of goiter, which is thyroid gland swelling, not specific to hypothyroidism. Therefore, the correct answer is C based on the characteristic symptoms of hypothyroidism.

Correct Answer: A

Rationale: The correct answer is A because evaluating a nursing intervention involves collecting data to determine if the goals set for the intervention were achieved. This process helps in assessing the effectiveness of the intervention in meeting the desired outcomes. Option B is incorrect as it refers to the identification of nursing diagnoses for new problems, which is part of the nursing assessment phase, not evaluation. Option C is incorrect as adjusting the care plan to include collaborative interventions is part of the implementation phase, not evaluation. Option D is incorrect as performing client care tasks as per protocol is part of the implementation phase, not evaluation.
