1. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?
- A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
- B. The healthcare team will wait until the client's family can be contacted for consent.
- C. The healthcare team will contact the hospital clergy to provide informed consent.
- D. The healthcare team will obtain consent from the client's legal guardian before proceeding.
Correct answer: A
Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.
2. What intervention should the nurse take for a client who has sustained a hyphema?
- A. Instruct the client to wear eye protectors in the future
- B. Keep the client at bed rest, typically with the head of the bed propped up
- C. Apply atropine eyedrops
- D. Apply an ice pack to the site of injury
Correct answer: B
Rationale: The correct intervention for a client who has sustained a hyphema is to keep them at bed rest, usually with the head of the bed raised. This positioning helps to reduce intraocular pressure and prevent further damage or rebleeding. Instructing the client to wear eye protectors in the future (Choice A) is not the immediate intervention required for a hyphema. Applying atropine eyedrops (Choice C) is not typically indicated for a hyphema. Applying an ice pack to the site of injury (Choice D) is not recommended for a hyphema as it can increase the risk of rebleeding. Therefore, the correct answer is to keep the client at bed rest.
3. 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.
4. 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.
5. Which sign might a healthcare professional observe in a client with a high ammonia level?
- A. coma
- B. edema
- C. hypoxia
- D. polyuria
Correct answer: A
Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.
