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-Barr© 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-Barr© 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.

Which action should the PN implement when using standard precautions to provide client care?
- A. Apply sterile gloves to obtain a finger stick blood sample
- B. Wear clean exam gloves to perform perineal catheter care
- C. Replace the needle cap after giving an intramuscular injection
- D. Wear a paper gown to prevent transmission of droplet pathogens
Correct Answer: B
Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.
An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the nurse document as evidence that the amount of insulin is inadequate?
- A. States that her feet are constantly cold and numb
- B. A wound on the ankle that starts to drain and becomes painful
- C. Consecutive evening serum glucose greater than 260 mg/dL
- D. Reports nausea in the morning but still able to eat breakfast
Correct Answer: C
Rationale: The correct answer is C. Consistently high evening glucose levels indicate that the current insulin dosage is inadequate to maintain proper glucose control. Choice A is incorrect because cold and numb feet are more indicative of peripheral vascular disease rather than inadequate insulin dosage. Choice B describes a wound that may be related to poor circulation or neuropathy but not necessarily inadequate insulin dosage. Choice D suggests gastrointestinal issues that are not directly related to insulin dosage adequacy.
When preparing a sterile field for a procedure, which action should the nurse take to maintain sterility?
- A. Place sterile items around the sterile field
- B. Keep hands below waist level to avoid contamination
- C. Open the sterile package away from the body
- D. Avoid reaching over the sterile field
Correct Answer: D
Rationale: To maintain sterility when preparing a sterile field, it is essential to avoid reaching over the sterile field. This action can introduce contaminants from the nurse's clothing or unsterile areas, compromising the sterility of the field. Placing sterile items around the sterile field (choice A) is incorrect as it may increase the risk of contamination by extending the area where non-sterile items may come in contact. Keeping hands below waist level (choice B) is also incorrect as it does not prevent contamination effectively. Opening the sterile package away from the body (choice C) is incorrect since it exposes the contents to the nurse's body, which is not sterile.
A nurse is reviewing the basal body temperature method with a couple. Which of the following statements would indicate that the teaching has been successful?
- A. I don't need to buy a special type of thermometer.
- B. I need to wait 5 minutes after smoking a cigarette before I take my temperature.
- C. I need to take my temperature before I get out of bed in the morning.
- D. I need to take my temperature at least once every day.
Correct Answer: C
Rationale: The correct answer is C. Basal body temperature must be taken before getting out of bed in the morning to get an accurate reading, as even slight activity can raise body temperature and affect the results. Choice A is incorrect because a special type of thermometer is not required for basal body temperature measurement. Choice B is incorrect because smoking can affect body temperature, but the timing mentioned is not relevant to basal body temperature measurement. Choice D is incorrect because while it is essential to take the temperature consistently each day, the duration of temperature measurement is not specified, making this choice less specific compared to the correct answer.
A client who had an abdominal hysterectomy is experiencing minimal urine output despite adequate fluid intake. What should the nurse assess first?
- A. The client's bladder for distension.
- B. The IV catheter insertion site.
- C. The patency of the urinary catheter.
- D. The client's vital signs.
Correct Answer: C
Rationale: Assessing the patency of the urinary catheter is crucial in this situation. A blocked catheter could be a common cause of decreased urine output following surgery. While checking the IV catheter insertion site (Choice B) is important, it is not the priority in this case. Examining the client's bladder for distension (Choice A) is relevant, but assessing the patency of the catheter takes precedence in resolving the issue of decreased urine output. Monitoring vital signs (Choice D) is a routine nursing task but not the priority when dealing with decreased urine output post-surgery.
