Question 1 of 5
All of the following muscles involved in wrist and finger extension receive innervation from the radial nerve except:
Correct Answer: C
Rationale: The correct answer is C: Extensor digiti minimi. The extensor digiti minimi muscle is innervated by the posterior interosseous nerve, a branch of the radial nerve. The other muscles listed (A, B, D) are all involved in wrist and finger extension and receive innervation from the radial nerve directly. Therefore, extensor digiti minimi is the exception as it is not innervated by the radial nerve, unlike the other muscles mentioned.
Question 2 of 5
When reviewing the concepts of health, the nurse recalls that the components of holistic health include which of these?
Correct Answer: D
Rationale: The correct answer is D because holistic health emphasizes the interconnectedness of the mind, body, and spirit, viewing them as interdependent aspects of an individual's overall well-being. This approach recognizes that all three components must be in balance for optimal health. Choice A is incorrect because disease can also originate internally. Choice B is incorrect as humans are influenced by their environment. Choice C is incorrect as multiple healthcare professionals contribute to a patient's health state, not just nurses.
Question 3 of 5
Which of the following is an indication for microwave diathermy?
Correct Answer: D
Rationale: The correct answer is D. Microwave diathermy is used to increase heat to muscles, joints, and tissues, aiding in pain relief, improving circulation, and promoting healing. Choice A is correct as it helps increase heat to muscles. Choice C is also correct as it helps increase heat to joints. Choice B is incorrect because microwave diathermy is not typically used for resolving hematomas, as other modalities like cold therapy are more effective. Therefore, D is the correct answer as it encompasses all the indications for microwave diathermy.
Question 4 of 5
You note that a patient has anisocoria (unequal pupil condition) on examination. Pathologic causes of this include which of the following?
Correct Answer: A
Rationale: The correct answer is A: Horner's syndrome. Anisocoria in Horner's syndrome is due to sympathetic nerve dysfunction, leading to a smaller pupil (miosis) in the affected eye. This occurs because of disruption in the sympathetic pathway, causing ptosis, anhidrosis, and miosis. Benign anisocoria (choice B) is a normal physiological variation in pupil size and does not involve pathologic causes. Differing light intensities for each eye (choice C) can cause temporary unequal pupil size but is not a pathologic cause. Eye prosthesis (choice D) is an artificial eye and not a cause of anisocoria.
Question 5 of 5
A young patient presents with a left-sided mass in her abdomen. You confirm that it is present in the left upper quadrant. Which of the following would support that this represents an enlarged kidney rather than her spleen?
Correct Answer: C
Rationale: The correct answer is C because the presence of normal tympany over the left upper quadrant indicates that gas-filled structures, such as the stomach or intestines, are present. This suggests that the mass is not the spleen, which is a solid organ that would produce dullness to percussion. A: A palpable 'notch' along its edge is more indicative of an enlarged spleen rather than a kidney. B: The inability to push your fingers between the mass and the costal margin suggests a mass that is closely adherent to the ribs, which could be seen in both enlarged kidney and spleen. D: The ability to push your fingers medial and deep to the mass could also be seen in both kidney and spleen enlargements.
