Nokea
The nurse has just administered a purified protein derivative (PPD) tuberculin skin test (Mantoux test) to a client who is at low risk for developing tuberculosis. The nurse determines that the test is positive if which occurs?
- A. An induration of 15 mm
- B. The presence of a wheal
- C. A large area of erythema
- D. Itching at the injection site
Correct Answer: A
Rationale: An induration of 10 mm or more is considered positive for clients in low-risk groups. The presence of a wheal would indicate that the skin test was administered appropriately. Erythema or itching at the site is not indicative of a positive reaction.

The nurse is caring for a client prescribed digoxin. Which manifestations correlate with a digoxin level of 2.3 ng/dL (2.93 nmol/L)? Select all that apply.
- A. Nausea
- B. Drowsiness
- C. Photophobia
- D. Increased appetite
- E. Increased energy level
- F. Seeing halos around bright objects
Correct Answer: A,B,C,F
Rationale: Digoxin is a cardiac glycoside used to manage and treat heart failure, control ventricular rate in clients with atrial fibrillation, and treat and prevent recurrent paroxysmal atrial tachycardia. The therapeutic range is 0.8 to 2.0 ng/mL (1.02 to 2.56 nmol/L). Signs of toxicity include gastrointestinal disturbances, including anorexia, nausea, and vomiting; neurological abnormalities such as fatigue, headache, depression, weakness, drowsiness, confusion, and nightmares; facial pain; personality changes; and ocular disturbances such as photophobia, halos around bright lights, and yellow or green color perception.
The nurse, caring for a client who has been placed in Buck's extension traction while awaiting surgical repair of a fractured femur, should perform a complete neurovascular assessment of the affected extremity that include which interventions? Select all that apply.
- A. Vital signs
- B. Bilateral lung sounds
- C. Pulse in the affected extremity
- D. Level of pain in the affected leg
- E. Skin color of the affected extremity
- F. Capillary refill of the affected toes
Correct Answer: C,D,E,F
Rationale: A complete neurovascular assessment of an extremity includes color, sensation, movement, capillary refill, and pulse of the affected extremity. Options 1 and 2 are not related to neurovascular assessment.
A client is admitted to the cardiac intensive care unit after coronary artery bypass graft (CABG) surgery. The nurse notes that in the first hour after admission, the mediastinal chest tube drainage was 75 mL. During the second hour, the drainage has dropped to 5 mL. The nurse interprets this data and implements which intervention?
- A. Identifies that the tube is draining normally
- B. Assesses the tube to locate a possible occlusion
- C. Auscultates the lungs for appropriate bilateral expansion
- D. Assists the client with frequent coughing and deep breathing
Correct Answer: B
Rationale: After CABG surgery, chest tube drainage should not exceed 100 to 150 mL per hour during the first 2 hours postoperatively, and approximately 500 mL of drainage is expected in the first 24 hours after CABG surgery. The sudden drop in drainage between the first and second hour indicates that the tube is possibly occluded and requires further assessment by the nurse. Options 1, 3, and 4 are incorrect interventions.
A multidisciplinary team working with the spouse of a home care client who has end-stage liver failure is teaching the spouse about pain management. Which statement by the spouse indicates the need for further teaching?
- A. My husband can use breathing exercises to control pain.
- B. I will help prevent constipation with increased fluids.
- C. If the pain increases, I will report it to the nurse promptly.
- D. The medication causes very deep sleep that my husband needs.
Correct Answer: D
Rationale: In the client with liver disease, the ability to metabolize medication is affected. A decreased level of consciousness is a potential clinical indicator of medication overdose, as well as fluid, electrolyte, and oxygenation deficiencies; thus, the nurse teaches the client's spouse about the differences between sleep related to pain relief and a deteriorating change in neurological status. Options 1, 2, and 3 all indicate an understanding of suitable steps to be taken in pain management.
A client arrives at the emergency department with upper gastrointestinal (GI) bleeding that began 3 hours ago. What is the priority action?
- A. Obtaining vital signs
- B. Inserting a nasogastric (NG) tube
- C. Asking the client about the precipitating events
- D. Completing an abdominal physical assessment
Correct Answer: A
Rationale: The priority action for the client with GI bleeding is to obtain vital signs to determine whether the client is in shock from blood loss and obtain a baseline by which to monitor the progress of treatment. The client may not be able to provide subjective data until the immediate physical needs are met. A complete abdominal physical assessment must be performed but is not the priority. Insertion of an NG tube may be prescribed but is not the priority action.
