The nurse reviews the results of a blood chemistry profile for a client who is experiencing late-stage salicylate poisoning and metabolic acidosis. Which serum study should the nurse review for data about the client's acid-base balance?
- A. Sodium
- B. Potassium
- C. Magnesium
- D. Phosphorus
Correct Answer: B
Rationale: A client with late-stage salicylate poisoning is at risk for metabolic acidosis because acetylsalicylic acid increases the client's hydrogen ion (H+) concentration, decreases the pH, and creates a bicarbonate deficit. Hyperkalemia develops as the body attempts to compensate for the influx of H+ by moving H+ into the cell and potassium out of the cell; thus, potassium accumulates in the extracellular space. Clinical manifestations of metabolic acidosis include the clinical indicators of hyperkalemia, including hyperpnea, central nervous system depression, twitching, and seizures. Options 1, 3, and 4 are not primary concerns.

The nurse is caring for a client who had an orthopedic injury of the leg that required surgery and the application of a cast. Postoperatively, which nursing assessment is of highest priority to assure client safety?
- A. Monitoring for heel breakdown
- B. Monitoring for bladder distention
- C. Monitoring for extremity shortening
- D. Monitoring for blanching ability of toe nail beds
Correct Answer: D
Rationale: With cast application, concern for compartment syndrome development is of the highest priority. If postsurgical edema compromises circulation, the client will demonstrate numbness, tingling, loss of blanching of toenail beds, and pain that will not be relieved by opioids. Although heel breakdown, bladder distention, or extremity lengthening or shortening can occur, these complications are not potentially life-threatening complications.
A client experiencing empyema is to have a bedside thoracentesis performed. The nurse plans to have which equipment available in the event that the procedure is not effective?
- A. Code cart
- B. A small-bore needle
- C. Extra-large drainage bottle
- D. Chest tube and drainage system
Correct Answer: D
Rationale: Empyema is the collection of pus within the pleural cavity. If the exudate is too thick for drainage via thoracentesis, the client may require placement of a chest tube to adequately drain the purulent effusion. A small-bore needle would not effectively allow exudate to drain. Options 1 and 3 are also unnecessary.
A child is admitted to the hospital with a diagnosis of rheumatic fever. The nurse reviews the blood laboratory findings, knowing that which finding will confirm the likelihood of this disorder?
- A. Increased leukocyte count
- B. Decreased hemoglobin count
- C. Increased antistreptolysin-O (ASO titer)
- D. Decreased erythrocyte sedimentation rate
Correct Answer: C
Rationale: Children suspected of having rheumatic fever are tested for streptococcal antibodies. The most reliable and best standardized test to confirm the diagnosis is the ASO titer. An elevated level indicates the presence of rheumatic fever. The remaining options are unrelated to diagnosing rheumatic fever. Additionally, an increased leukocyte count indicates the presence of infection but is not specific in confirming a particular diagnosis.
The emergency department nurse is assessing a client who abruptly discontinued benzodiazepine therapy and is experiencing withdrawal. Which manifestations of withdrawal should the nurse expect to note? Select all that apply.
- A. Tremors
- B. Sweating
- C. Lethargy
- D. Agitation
- E. Nervousness
- F. Muscle weakness
Correct Answer: A,B,D,E
Rationale: Benzodiazepines should not be abruptly discontinued because withdrawal symptoms are likely to occur. Withdrawal symptoms include tremor, sweating, agitation, nervousness, insomnia, anorexia, and muscular cramps. Withdrawal symptoms from long-term, high-dose benzodiazepine therapy include paranoia, delirium, panic, hypertension, and status epilepticus. Lethargy is not associated with benzodiazepine withdrawal.
The nurse is encouraging the client to cough and deep breathe after cardiac surgery. The nurse ensures that which item is available to maximize the effectiveness of this procedure?
- A. Nebulizer
- B. Ambu bag
- C. Suction equipment
- D. Incisional splinting pillow
Correct Answer: D
Rationale: The use of an incisional splint such as a 'cough pillow' can ease discomfort during coughing and deep breathing. The client who is comfortable will do more effective deep breathing and coughing exercises. Use of an incentive spirometer is also indicated. Options 1, 2, and 3 will not encourage the client to cough and deep breathe.
