Nursing Elites

1. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?

• A. Crossed-extensor reflex
• B. Flexor reflex
• C. Withdrawal reflex
• D. Stretch reflex

Correct answer: C

Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.

2. The parents of a 4-year-old girl have sought care because their daughter has admitted to chewing and swallowing imported toy figurines that have been determined to be made of lead. Which of the following blood tests should the care team prioritize?

• A. White blood cell levels with differential
• B. Red blood cell levels and morphology
• C. Urea and creatinine levels
• D. Liver function panel

Correct answer: B

Rationale: The correct answer is B: Red blood cell levels and morphology. Lead poisoning primarily affects red blood cells, causing anemia. Therefore, the priority test would be to assess red blood cell levels and morphology. Choice A (White blood cell levels with differential) is incorrect as lead poisoning does not primarily affect white blood cells. Choice C (Urea and creatinine levels) is unrelated to lead poisoning and not a priority in this scenario. Choice D (Liver function panel) is also not the priority as lead poisoning's primary impact is on the red blood cells, not the liver.

3. A toddler is displaying signs/symptoms of weakness and muscle atrophy. The pediatric neurologist suspects it may be a lower motor neuron disease called spinal muscular atrophy (SMA). The client's family asks how he got this. The nurse will respond:

• A. This could result from playing in soil and then ingesting bacteria that is now attacking his motor neurons.
• B. No one really knows how this disease is formed. We just know that in time, he may grow out of it.
• C. This is a degenerative disorder that tends to be inherited as an autosomal recessive trait.
• D. This is a segmental demyelination disorder that affects all nerve roots and eventually all muscle groups as well.

Correct answer: C

Rationale: The correct answer is C. Spinal muscular atrophy (SMA) is an inherited disorder, often autosomal recessive, that affects lower motor neurons. Choice A is incorrect because SMA is not caused by ingesting bacteria from playing in soil. Choice B is incorrect as SMA is not something that a person grows out of. Choice D is incorrect because SMA is not a demyelination disorder that affects nerve roots and muscle groups.

4. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?

• A. Hypotonia
• B. Hyperreflexia
• C. Muscle atrophy
• D. Fasciculations

Correct answer: B

Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.

5. What is the most common cause of cancer-related deaths in both men and women?

• A. Lung cancer
• B. Breast cancer
• C. Colorectal cancer
• D. Prostate cancer

Correct answer: A

Rationale: Lung cancer is the leading cause of cancer-related deaths in both men and women globally. It is strongly associated with smoking and exposure to environmental toxins. Breast cancer (choice B) primarily affects women, while colorectal cancer (choice C) and prostate cancer (choice D) are more gender-specific. Colorectal cancer is more common in both men and women but not the leading cause of cancer-related deaths.
