The nurse determines that a tuberculin skin test is positive. Which diagnostic test should the nurse anticipate will be prescribed to confirm a diagnosis tuberculosis (TB)?
- A. Chest x-ray
- B. Sputum culture
- C. Complete blood cell count
- D. Computed tomography scan of the chest
Correct Answer: B
Rationale: Although the findings of the chest x-ray examination are important, it is not possible to make a diagnosis of TB solely on the basis of this examination because other diseases can mimic the appearance of TB. The demonstration of tubercle bacilli bacteriologically is essential for establishing a diagnosis. The microscopic examination of sputum for acid-fast bacilli is usually the first bacteriological evidence of the presence of tubercle bacilli. Options 3 and 4 will not diagnose TB.

The nurse is preparing to care for an infant diagnosed with pertussis. Which priority problem should the nurse address when planning care?
- A. Infection
- B. Fluid overload
- C. Impaired sleep patterns
- D. Inability to expectorate secretions
Correct Answer: D
Rationale: The priority problem for the child with pertussis relates to adequate air exchange. Because of the copious, thick secretions that occur with pertussis and the small airways of an infant, air exchange is critical. Infection is an important consideration, but airway is the priority. A deficient fluid volume is more likely to occur in this infant because of the thick secretions and vomiting. Sleep patterns may be disturbed because of the coughing, but this is not the critical issue.
The nurse is informed that a newborn infant whose mother is Rh negative will be admitted to the nursery. When planning care for the infant's arrival, which action should the nurse take?
- A. Obtain the newborn infant's blood type and direct Coombs' results from the laboratory.
- B. Obtain the necessary equipment from the blood bank needed for an exchange transfusion.
- C. Call the maintenance department and ask for a phototherapy unit to be brought to the nursery.
- D. Obtain a vial of vitamin K from the pharmacy and prepare to administer an injection to prevent isoimmunization.
Correct Answer: A
Rationale: To further plan for the newborn infant's care, the infant's blood type and direct Coombs' results must be known. Umbilical cord blood is taken at the time of delivery to determine blood type, Rh factor, and antibody titer (direct Coombs' test) of the newborn infant. The nurse should obtain these results from the laboratory. Options 2 and 3 are inappropriate at this time, and additional data are needed to determine whether these actions are needed. Option 4 is incorrect because vitamin K is given to prevent hemorrhagic disease of the newborn infant.
A client is admitted to a mental health unit with a diagnosis of anorexia nervosa. When planning care for this client, which primary intervention should health promotion focus on?
- A. Providing a supportive environment
- B. Examining intrapsychic conflicts and past issues
- C. Emphasizing social interaction with clients who are withdrawn
- D. Helping the client identify and examine dysfunctional thoughts and beliefs
Correct Answer: D
Rationale: Health promotion focuses on helping clients identify and examine dysfunctional thoughts, as well as identifying and examining the values and beliefs that maintain these thoughts. Providing a supportive environment is important, but it is not as primary as option 4 for this client. Examining intrapsychic conflicts and past issues is not directly related to the client's problem. Emphasizing social interaction is not appropriate at this time.
The nurse is receiving a client from the emergency department who has a diagnosis of Guillain-Barré syndrome. The client's chief sign/symptom is an ascending paralysis that has reached the level of the waist. Which items should the nurse plan to have available for emergency use?
- A. Nebulizer and pulse oximeter
- B. Blood pressure cuff and flashlight
- C. Flashlight and incentive spirometer
- D. Cardiac monitor and intubation tray
Correct Answer: D
Rationale: The client with Guillain-Barré syndrome is at risk for respiratory failure as a result of ascending paralysis. An intubation tray should be available for emergency use. Another complication of this syndrome is cardiac dysrhythmias, which necessitates the need for cardiac monitoring. Although some of the items in the remaining options may be kept at the bedside (e.g., pulse oximeter, blood pressure cuff, flashlight), they are not necessarily needed for emergency use in this situation.
A client is experiencing diabetes insipidus as a result of cranial surgery. Which anticipated therapy should the nurse plan to implement?
- A. Fluid restriction
- B. Administering diuretics
- C. Increased sodium intake
- D. Intravenous (IV) replacement of fluid losses
Correct Answer: D
Rationale: The client with diabetes insipidus excretes large amounts of extremely dilute urine. This usually occurs as a result of decreased synthesis or the release of antidiuretic hormone in clients with conditions such as head injury, surgery near the hypothalamus, or increased intracranial pressure. Corrective measures include allowing ample oral fluid intake, administering IV fluid as needed to replace sensible and insensible losses, and administering vasopressin. Diuretics are not administered. Sodium is not administered because the serum sodium level is usually high, as is the serum osmolality.
