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 teaches a postpartum client about postdelivery lochia. The nurse determines that the education has been effective when the client says that on the second day postpartum, the lochia should be which color?
- A. Red
- B. Pink
- C. White
- D. Yellow
Correct Answer: A
Rationale: The uterus rids itself of the debris that remains after birth through a discharge called lochia, which is classified according to its appearance and contents. Lochia rubra is dark red in color. It occurs from delivery to 3 days postpartum and contains epithelial cells, erythrocytes, leukocytes, shreds of decidua, and occasionally fetal meconium, lanugo, and vernix caseosa. Lochia serosa is a brownish pink discharge that occurs from days 4 to 10. Lochia alba is a white discharge that occurs from days 10 to 14. Lochia should not be yellow or contain large clots; if it does, the cause should be investigated without delay.
A hospitalized client awaiting repair of an unruptured cerebral aneurysm is frequently assessed by the nurse. Which assessment finding should the nurse identify as an early indication that the aneurysm has ruptured?
- A. Widened pulse pressure
- B. Unilateral motor weakness
- C. Unilateral slowing of pupil response
- D. A decline in the level of consciousness
Correct Answer: D
Rationale: Rupture of a cerebral aneurysm usually results in increased intracranial pressure (ICP). The first sign of pressure in the brain is a change in the level of consciousness. This change in consciousness can be as subtle as drowsiness or restlessness. Because centers that control blood pressure are located lower in the brain than those that control consciousness, blood pressure alteration is a later sign. Slowing of pupil response and motor weakness are also late signs.
A client diagnosed with acute respiratory distress syndrome has a prescription to be placed on a continuous positive airway pressure (CPAP) face mask. What intervention should the nurse implement for this procedure to be beneficial?
- A. Obtain baseline arterial blood gases.
- B. Obtain baseline pulse oximetry levels.
- C. Apply the mask to the face with a snug fit.
- D. Remove the mask for deep breathing exercises.
Correct Answer: C
Rationale: The CPAP face mask must be applied over the nose and mouth with a snug fit, which is necessary to maintain positive pressure in the client's airways. The nurse obtains baseline respiratory assessments and arterial blood gases to evaluate the effectiveness of therapy, but these are not done to increase the effectiveness of the procedure. A disadvantage of the CPAP face mask is that the client must remove it for coughing, eating, or drinking. This removes the benefit of positive pressure in the airway each time it is removed.
The nurse is caring for a client who is receiving blood transfusion therapy. Which clinical manifestations should alert the nurse to a hemolytic transfusion reaction? Select all that apply.
- A. Headache
- B. Tachycardia
- C. Hypertension
- D. Apprehension
- E. Distended neck veins
- F. A sense of impending doom
Correct Answer: A,B,D,F
Rationale: Hemolytic transfusion reactions are caused by blood type or Rh incompatibility. When blood containing antigens different from the client's own antigens is infused, antigen-antibody complexes are formed in the client's blood. These complexes destroy the transfused cells and start inflammatory responses in the client's blood vessel walls and organs. The reaction may include fever and chills or may be life-threatening with disseminated intravascular coagulation and circulatory collapse. Other manifestations include headache, tachycardia, apprehension, a sense of impending doom, chest pain, low back pain, tachypnea, hypotension, and hemoglobinuria. The onset may be immediate or may not occur until subsequent units have been transfused. Distended neck veins are characteristics of circulatory overload.
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.
