ATI Fluid and Electrolytes
1. What is the fluid inside the cell called?
- A. Plasma
- B. Intracellular fluid
- C. Interstitial fluid
- D. Plasma and intracellular fluid
Correct answer: B
Rationale: The correct answer is 'Intracellular fluid.' Intracellular fluid refers to the fluid contained within the cells, constituting a significant portion of the body's total water content. Choices A, C, and D are incorrect. Plasma is the liquid component of blood outside the cells, interstitial fluid is the fluid surrounding cells in tissues, and the combination of plasma and intracellular fluid is not the specific term for the fluid inside the cell.
2. A parent brings their 2-year-old son in for a well visit. The nurse assesses his growth since the last appointment. Which finding should concern the nurse?
- A. Prominent abdomen
- B. Forward curve of the spine in the sacral area
- C. Increase in height of 5 inches in the past year
- D. Total weight gain of 15 lb in the past year
Correct answer: D
Rationale: The correct answer is D. A total weight gain of 15 lb in one year for a 2-year-old is excessive and may indicate an underlying issue such as a metabolic disorder or overfeeding. This rapid weight gain can put the child at risk for health problems. Choices A, B, and C are not typically concerning findings in a 2-year-old. A prominent abdomen can be normal at this age due to a toddler's slightly protruding belly, a forward curve of the spine at the sacral area is a typical finding in young children, and an increase in height of 5 inches in a year is within the expected range of growth for a 2-year-old.
3. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: Respiratory alkalosis
Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.
4. What information should the nurse provide in patient education for a patient prescribed sertraline for major depressive disorder?
- A. Take the medication with food.
- B. It may take several weeks to feel the full effect.
- C. Avoid consuming grapefruit while taking this medication.
- D. Regular blood tests are necessary to monitor levels.
Correct answer: B
Rationale: Patients prescribed sertraline for major depressive disorder should be educated that it may take several weeks before experiencing the full therapeutic effects of the medication. This delay in onset of action is common with antidepressants like sertraline, and patients need to be aware of this to manage their expectations and continue with the treatment regimen. It's important for the patient to understand that consistent adherence to the prescribed dosage is crucial, even if the full effects are not immediately apparent. Choices A, C, and D are incorrect because taking the medication with food, avoiding grapefruit, and regular blood tests are not specific education points related to the expected timeframe for therapeutic effects of sertraline.
5. While making rounds, the nurse observes the following client behaviors. Which child should the nurse further evaluate for postoperative pain?
- A. The 6-month-old in deep sleep
- B. The 2-year-old who is cooperative when the nurse takes vital signs
- C. The 4-year-old who is actively watching cartoons
- D. The 14-month-old who is screaming and thrashing his arms and legs
Correct answer: D
Rationale: The correct answer is D because screaming and thrashing his arms and legs are indicative behaviors of discomfort or pain in young children. The child's actions suggest a higher likelihood of experiencing postoperative pain and necessitate further evaluation. Choices A, B, and C do not exhibit overt signs of distress or discomfort associated with pain, making them less likely candidates for postoperative pain assessment.
