The nurse is assessing the pulses of a patient who has been admitted for untreated hyperthyroidism. The nurse should expect to find a(n) _____ pulse.

Correct Answer: C

Rationale: The correct answer is C: Bounding. In hyperthyroidism, there is an excess of thyroid hormones which can lead to an increased heart rate and force of contraction. Bounding pulse refers to a strong and forceful pulse, which is expected in hyperthyroidism due to the increased cardiac output. Normal pulse (A) would not be expected as the heart rate is usually elevated in hyperthyroidism. Absent pulse (B) is not appropriate as hyperthyroidism typically leads to an increased pulse. Weak, thready pulse (D) is not expected as the increased cardiac output in hyperthyroidism usually results in a strong pulse.

Correct Answer: A

Rationale: The correct answer is A: Hemianopsia. This is because filling only the numbers on the right half of the clock suggests a visual field defect on the left side, a common symptom of hemianopsia. This could indicate damage to the brain's visual processing areas, such as in stroke or brain injury. Fatigue (B), Oppositional defiant disorder (C), and Depression (D) are unlikely to cause this specific symptom and should be ruled out through further assessment.

Correct Answer: C

Rationale: Objective data are measurable and observable, not based on personal feelings or interpretations. Choice C, "Clear breath sounds," is objective data because it can be directly heard and assessed by a healthcare provider. Feeling dizzy (A) and headache (D) are subjective symptoms reported by the patient, making them subjective data. Complaints of nausea (B) are also subjective as they are based on the patient's personal experience and cannot be directly observed or measured by a healthcare provider. Therefore, choice C is the correct answer as it represents objective data that can be observed and measured.

Correct Answer: B

Rationale: The patellar tendon reflex is mediated by the femoral nerve, which receives sensory input from the L4 nerve root. When the patellar tendon is tapped, the sensory information is transmitted via the L4 nerve root to the spinal cord, activating the motor response through the femoral nerve. Therefore, the correct answer is B: L4. A: L1 - Incorrect. The L1 nerve root does not innervate the patellar tendon reflex. C: L5 - Incorrect. The L5 nerve root does not play a direct role in the patellar tendon reflex. D: S1 - Incorrect. The S1 nerve root is not involved in the patellar tendon reflex pathway.

Correct Answer: C

Rationale: The correct answer is C: Brachialis. The brachialis muscle is the main flexor of the forearm as it lies deep to the biceps brachii and directly acts on the ulna to flex the elbow joint. It is responsible for flexing the forearm regardless of the position of the hand. The other choices are incorrect because: A. Anconeus is a small muscle involved in extension of the elbow, not flexion. B. Biceps brachii is a powerful supinator of the forearm and also assists in flexion, but it is not the main flexor. D. Brachioradialis is a synergist in forearm flexion but not the primary flexor.
