1. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

• A. Brown-S�quard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

2. A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?

• A. positive
• B. false positive
• C. negative
• D. false negative

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.

3. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

4. When observing a dressing change by a graduate nurse on a Stage III pressure ulcer to the greater trochanter by the staff nurse, a need for further teaching is indicated after the following observation by the nurse:

• A. The new graduate nurse irrigates the pressure ulcer with 50cc of NS.
• B. The new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide.
• C. The new graduate packs the wound with sterile kerlix soaked in NS.
• D. The new graduate applies a Duoderm dressing over the wound after cleansing.

Correct answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.

5. Which is the proper hand position for performing chest percussion?

• A. Use the side of the hands
• B. Flatten the hands
• C. Spread the fingers of both hands
• D. Cup the hands

Correct answer: D

Rationale: The proper hand position for performing chest percussion is to cup the hands. Cupping the hands helps produce a vibration that aids in loosening respiratory secretions effectively. This technique is essential for therapeutic chest physiotherapy. Using the side of the hands, flattening the hands, or spreading the fingers of both hands do not generate the necessary vibration required for chest percussion. These hand positions are not considered proper techniques in this context and may not provide the desired therapeutic effect.
