1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

2. What is the most appropriate feeding method for a client who is unable to swallow?

• A. Nothing by mouth
• B. Nasogastric feedings
• C. Clear liquids
• D. Total parenteral nutrition

Correct answer: B

Rationale: Nasogastric feedings are the most appropriate feeding method for a client who is unable to swallow. Providing nothing by mouth can lead to nutritional deficiencies, while clear liquids might cause aspiration. Total parenteral nutrition is not necessary if the gastrointestinal tract is functional. Nasogastric feedings are preferred as they can safely provide nutrition without the risks associated with not eating or aspirating.

3. What is mammography used to detect?

• A. pain
• B. tumor
• C. edema
• D. epilepsy

Correct answer: B

Rationale: Mammography is a diagnostic imaging technique specifically designed to detect tumors, cysts, or other abnormalities in breast tissue. It is not used to detect pain, edema, or epilepsy. Pain is a symptom, not a condition that mammography can detect. Edema refers to swelling and is not detectable through mammography. Epilepsy is a neurological disorder, not a condition detected by mammography.

4. Which of the following symptoms is not indicative of autonomic dysreflexia in the client with a spinal cord injury?

• A. sudden onset of headache
• B. flushed face
• C. hypotension
• D. nasal congestion

Correct answer: C

Rationale: Autonomic dysreflexia is characterized by a sudden onset of symptoms due to an overactive autonomic nervous system. Hypotension is not indicative of autonomic dysreflexia; instead, hypertension is a hallmark sign. Therefore, hypotension is the correct answer. Flushed face, sudden onset of headache, and nasal congestion are classic symptoms of autonomic dysreflexia caused by a noxious stimulus below the level of the spinal cord injury. These symptoms result from the body's attempt to regulate blood pressure when the normal feedback loop is interrupted.

5. When are standard walkers typically used?

• A. When clients have poor balance, cannot stand up, have weak arms, and good hand strength.
• B. When clients have poor balance, have a broken leg, or have experienced amputation.
• C. When clients have poor balance, have cardiac problems, or cannot use crutches or a cane.
• D. When clients have poor balance, have an autoimmune disease, or have weak arms.

Correct answer: C

Rationale: Standard walkers are typically used for clients who have poor balance, cardiac problems, or those who cannot use crutches or a cane. The rationale is correct in stating that a walker is suitable for individuals needing to bear partial weight and having strength in their wrists and arms to propel the walker forward. Choices A, B, and D are incorrect because they do not accurately reflect the main reasons why standard walkers are used in clinical practice. Using a walker is not solely about having weak arms, good hand strength, a broken leg, experienced amputation, or an autoimmune disease. The primary focus is on addressing balance issues, cardiac problems, or the inability to use crutches or a cane effectively.
