1. Which condition is characterized by a progressive loss of muscle strength due to an autoimmune attack on acetylcholine receptors?

• A. Myasthenia gravis
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis
• D. Guillain-Barré syndrome

Correct answer: A

Rationale: The correct answer is A: Myasthenia gravis. Myasthenia gravis is characterized by muscle weakness caused by autoimmune attack on acetylcholine receptors at the neuromuscular junction. This results in impaired communication between nerves and muscles. Choice B, Multiple sclerosis, is a condition where the immune system attacks the protective myelin sheath covering the nerves in the central nervous system, leading to communication issues between the brain and the rest of the body. Choice C, Amyotrophic lateral sclerosis, is a progressive neurodegenerative disease affecting motor neurons in the brain and spinal cord, not involving acetylcholine receptors. Choice D, Guillain-Barré syndrome, is an acute condition where the immune system attacks the peripheral nerves, causing muscle weakness and paralysis, but it does not target acetylcholine receptors.

2. While performing an inspection of a client's fingernails, the PN observes a suspected abnormality of the nail's shape and character. Which finding should the PN document?

• A. Clubbed nails
• B. Splinter hemorrhages
• C. Longitudinal ridges
• D. Koilonychia or spoon nails

Correct answer: A

Rationale: The correct answer is A: Clubbed nails. Clubbed nails are a significant finding often associated with chronic hypoxia or lung disease. The presence of clubbed nails should be documented for further evaluation. Splinter hemorrhages (Choice B) are tiny areas of bleeding under the nails and are associated with conditions like endocarditis. Longitudinal ridges (Choice C) are common and often a normal finding in older adults. Koilonychia or spoon nails (Choice D) refer to nails that are concave or scooped out, often seen in conditions like iron deficiency anemia or hemochromatosis. These conditions are not typically associated with chronic hypoxia or lung disease, making them less likely findings in this situation.

3. When assisting an older male client recovering from a stroke to ambulate with a cane, where should the nurse place the cane in relation to the client's body?

• A. In front of the body to lean on while stepping forward
• B. On the opposite side of the affected extremity
• C. Approximately one foot away from the body to stabilize balance
• D. On the same side as the affected extremity

Correct answer: B

Rationale: The correct answer is B: 'On the opposite side of the affected extremity.' Placing the cane on the opposite side of the affected extremity provides maximum support and stability during ambulation for a client recovering from a stroke. This positioning helps to offload weight from the affected side and improves balance. Choice A is incorrect because placing the cane in front of the body can lead to incorrect weight distribution and instability. Choice C is incorrect as placing the cane one foot away from the body may not provide adequate support and can compromise balance. Choice D is incorrect as placing the cane on the same side as the affected extremity does not offer the necessary balance and support needed for safe ambulation.

4. In obtaining an orthostatic vital sign measurement, what action should the nurse take first?

• A. Count the client's radial pulse
• B. Apply a blood pressure cuff
• C. Instruct the client to lie supine
• D. Assist the client to stand upright

Correct answer: C

Rationale: The correct first action when obtaining an orthostatic vital sign measurement is to instruct the client to lie supine. This allows for establishing a baseline measurement of vital signs before any positional changes. Counting the client's radial pulse (Choice A) is a step that follows after the initial supine position to assess changes in pulse rate. Applying a blood pressure cuff (Choice B) and assisting the client to stand upright (Choice D) are actions that come later in the process after the baseline measurements are obtained in the supine position.

5. A registered nurse is preparing to hang the first bag of total parenteral nutrition (TPN) solution. The client has a central line, and this is the first bag he will receive. Which of the following is the most essential piece of equipment to obtain prior to hanging the bag?

• A. Blood glucose meter
• B. Noninvasive blood pressure monitor
• C. Electronic infusion pump
• D. Urine test strips

Correct answer: C

Rationale: An electronic infusion pump is essential for administering TPN to ensure accurate delivery and avoid complications such as fluid overload or improper nutrient delivery. The pump helps regulate the flow rate precisely, which is crucial when infusing TPN. Monitoring the client's blood glucose is important but not immediately necessary before hanging the TPN bag. A noninvasive blood pressure monitor is not directly related to administering TPN and is not the most essential equipment needed for this procedure. Urine test strips are not required for administering TPN via a central line and are not essential equipment for this specific task.
