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. During a blood transfusion, which sign or symptom should prompt the healthcare provider to immediately stop the transfusion?

• A. Slight increase in blood pressure
• B. Elevated temperature and chills
• C. Mild nausea
• D. Slight headache

Correct answer: B

Rationale: The correct answer is B: Elevated temperature and chills. These symptoms are indicative of a transfusion reaction, which can be severe and life-threatening. It is crucial to stop the transfusion immediately and notify the healthcare provider for further assessment and management. Elevated temperature and chills are classic signs of a transfusion reaction, specifically indicating a possible febrile non-hemolytic reaction. Choice A, a slight increase in blood pressure, is not typically a reason to stop a transfusion unless it is a significant sudden increase. Mild nausea (Choice C) and a slight headache (Choice D) are common side effects of blood transfusions and are not primary indicators of a transfusion reaction that require immediate cessation of the transfusion.

3. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the PN to review?

• A. Hemoglobin and Hematocrit
• B. Serum Calcium
• C. Serum Creatinine
• D. WBC

Correct answer: C

Rationale: Serum creatinine is the most important lab value to review before administering an antibiotic that can cause nephrotoxicity. This is because serum creatinine is a key indicator of kidney function. An elevated serum creatinine level may indicate impaired renal function, and administering nephrotoxic drugs in such situations can further damage the kidneys. Monitoring serum creatinine levels helps healthcare providers assess renal function and make informed decisions regarding drug administration. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity, making them less crucial in this scenario. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels are more related to bone health and nerve function, and WBC count is associated with immune response, none of which directly reflect kidney function or the risk of nephrotoxicity.

4. A client is recovering from a right-sided mastectomy and is concerned about lymphedema. What should the nurse include in the discharge teaching to minimize this risk?

• A. Encourage wearing tight clothing on the affected arm.
• B. Advise against lifting heavy objects with the affected arm.
• C. Recommend the client sleep on the affected side.
• D. Suggest frequent massage of the affected arm.

Correct answer: B

Rationale: The correct answer is B: Advise against lifting heavy objects with the affected arm. Lifting heavy objects with the affected arm can increase the risk of lymphedema. It is important for clients to avoid activities that strain the affected arm to minimize the risk of developing lymphedema. Choices A, C, and D are incorrect because wearing tight clothing on the affected arm, sleeping on the affected side, and frequent massage of the affected arm can potentially worsen lymphedema or impede the recovery process. Tight clothing can impede lymphatic flow, sleeping on the affected side can restrict circulation, and frequent massage can exacerbate swelling in the arm.

5. What is the first action a healthcare professional should take when a patient’s nasogastric (NG) tube becomes clogged?

• A. Flush the tube with water
• B. Reposition the patient
• C. Attempt to aspirate the clog with a syringe
• D. Administer a medication to dissolve the clog

Correct answer: C

Rationale: When a patient's nasogastric (NG) tube becomes clogged, the first action to take is to attempt to aspirate the clog with a syringe. This is a standard and initial step to clear the blockage in the tube. Flushing the tube with water (Choice A) may not address the specific clog; repositioning the patient (Choice B) is not directly related to clearing the tube. Administering a medication to dissolve the clog (Choice D) should only be considered after simpler methods like aspiration have been attempted.
