Nokea
The client is being evaluated to rule out myasthenia gravis and being administered the Tensilon (edrophonium chloride) test. Which response to the test indicates the client has myasthenia gravis?
- A. The client has no apparent change in the assessment data.
- B. There is increased amplitude of electrical stimulation in the muscle.
- C. The circulating acetylcholine receptor antibodies are decreased.
- D. The client shows a marked improvement of muscle strength.
Correct Answer: D
Rationale: The Tensilon test improves muscle strength in myasthenia gravis by inhibiting acetylcholinesterase. No change, electrical stimulation, or antibody levels are not diagnostic.

Which assessment data should make the nurse suspect the client has chronic allergies?
- A. Jaundiced sclera and jaundiced palms of hands.
- B. Pale, boggy, edematous nasal mucosa.
- C. Lacy white plaques on the oral mucosa.
- D. Purple or blue patches on the face.
Correct Answer: B
Rationale: Pale, boggy, edematous nasal mucosa indicates chronic allergic rhinitis. Jaundice, oral plaques, and facial patches suggest other conditions.
The nurse is admitting a client diagnosed with protein-calorie malnutrition secondary to AIDS. Which intervention should be the nurse's first intervention?
- A. Assess the client's body weight and ask what the client has been able to eat.
- B. Place in contact isolation and don a mask and gown before entering the room.
- C. Check the HCP's orders and determine what laboratory tests will be done.
- D. Teach the client about total parenteral nutrition and monitor the subclavian IV site.
Correct Answer: A
Rationale: Assessing weight and dietary intake provides baseline data for malnutrition management. Isolation is unnecessary, lab orders are secondary, and TPN teaching is premature.
The nurse in the emergency department is allergic to latex. Which intervention should the nurse implement regarding the use of nonsterile gloves?
- A. Use only sterile, nonlatex gloves for any procedure requiring gloves.
- B. Do not use gloves when starting an IV or performing a procedure.
- C. Keep a pair of nonsterile, nonlatex gloves in the pocket of the uniform.
- D. Wear white cotton gloves at all times to protect the hands.
Correct Answer: C
Rationale: Carrying nonsterile, nonlatex gloves ensures safe practice for a latex-allergic nurse. Sterile gloves are unnecessary, avoiding gloves risks infection, and cotton gloves are inadequate.
The client diagnosed with an anaphylactic reaction is admitted to the emergency department. Which assessment data indicate the client is not responding to the treatment?
- A. The client has a urinary output of 120 mL in two (2) hours.
- B. The client has an AP of 110 and a BP of 90/60.
- C. The client has clear breath sounds and an RR of 26.
- D. The client has hyperactive bowel sounds.
Correct Answer: B
Rationale: Hypotension (BP 90/60) and tachycardia (AP 110) indicate ongoing anaphylaxis despite treatment. Normal urine output, clear lungs, and bowel sounds suggest improvement.
The primary nurse is administering medications to the assigned clients. Which client situation requires immediate intervention by the charge nurse?
- A. The client with congestive heart failure with an apical pulse of 64 who received 0.125 mg digoxin, a cardiac glycoside.
- B. The client with essential hypertension who received a beta blocker and has a blood pressure of 114/80.
- C. The client with myasthenia gravis who received the anticholinesterase medication 30 minutes late.
- D. The client with AIDS who received trimethoprim-sulfamethoxazole, an antibiotic, and has a CD4 cell count of less than 200.
Correct Answer: C
Rationale: A 30-minute delay in anticholinesterase for myasthenia gravis risks muscle weakness exacerbation, requiring intervention. Digoxin, beta blocker, and antibiotic administration are appropriate.
