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 in the prenatal clinic is monitoring a client who is pregnant with twins. The nurse monitors the client closely for which priority complication that is associated with a twin pregnancy?
- A. Hemorrhoids
- B. Postterm labor
- C. Maternal anemia
- D. Costovertebral angle tenderness
Correct Answer: C
Rationale: Maternal anemia often occurs in twin pregnancies because of a greater demand for iron by the fetuses. Options 1 and 4 occur in a twin pregnancy but would not be as high a priority as anemia. Option 2 is incorrect because twin pregnancies often end in prematurity.
A client has had a nasointestinal (NI) tube in place for 24 hours. Which assessment finding indicates that the tube is properly located in the intestine?
- A. Bowel sounds are absent.
- B. The client denies being nauseous.
- C. Aspirate from the tube has a pH of 7.
- D. The abdominal x-ray indicates that the end of the tube is above the pylorus.
Correct Answer: C
Rationale: The nasogastric (NG) or NI tube is used to decompress the intestine and correct a bowel obstruction. Nausea should subside as decompression is accomplished. The pH of the gastric fluid is acidic, and the pH of the intestinal fluid is alkaline (7 or higher). Although bowel sounds will be abnormal in the presence of obstruction, the presence or absence of bowel sounds is not associated with the location of the tube. The end of the tube should be located in the intestine (below the pylorus). Location of the tube can also be determined by radiographs.
The nurse reviews a primary health care provider's prescriptions and notes that a topical nitrate is prescribed. The nurse notes that acetaminophen is prescribed to be administered before the nitrate. The nurse implements the prescription with which understanding about why acetaminophen is prescribed?
- A. Headache is a common side effect of nitrates.
- B. Fever usually accompanies myocardial infarction.
- C. Acetaminophen potentiates the therapeutic effect of nitrates.
- D. Acetaminophen does not interfere with platelet action as acetylsalicylic acid (aspirin) does.
Correct Answer: A
Rationale: Headache occurs as a side effect of nitrates in many clients. Acetaminophen may be administered before nitrates to prevent headaches or minimize the discomfort from the headaches.
An assessment of a client's vocal cords requires indirect visualization of the larynx. Which instruction should the nurse give the client to facilitate this procedure?
- A. Try to swallow.
- B. Hold your breath.
- C. Breathe normally.
- D. Roll the tongue to the back of the mouth.
Correct Answer: C
Rationale: Indirect laryngoscopy is done to assess the function of the vocal cords or obtain tissue for biopsy. Observations are made during rest and phonation by using a laryngeal mirror, head mirror, and light source. The client is placed in an upright position to facilitate passage of the laryngeal mirror into the mouth and is instructed to breathe normally. Swallowing cannot be done with the mirror in place. The procedure takes longer than the time the client would be able to hold the breath, and this action is ineffective anyway. The tongue cannot be moved back because it would occlude the airway.
The nurse provides dietary instructions to a client who needs to limit intake of sodium. The nurse instructs the client that which food items must be avoided because of their high sodium content? Select all that apply.
- A. Ham
- B. Apples
- C. Broccoli
- D. Soy sauce
- E. Asparagus
- F. Cantaloupe
Correct Answer: A,D
Rationale: Foods highest in sodium include table salt, some cheeses, soy sauce, cured pork, canned foods because of the preservatives, and foods such as cold cuts. Fruits and vegetables contain minimal amounts of sodium.
