1. A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor while the patient is receiving this infusion?
- A. Lung sounds
- B. Urinary output
- C. Peripheral pulses
- D. Peripheral edema
Correct answer: A
Rationale: The correct answer is A: Lung sounds. Hypertonic solutions like 3% NaCl can cause water retention, leading to fluid excess. Monitoring lung sounds is crucial as crackles may indicate pulmonary edema, a serious manifestation of fluid excess. While monitoring urinary output, peripheral pulses, and peripheral edema are also important when administering hypertonic solutions, they do not provide immediate clues to acute respiratory or cardiac decompensation like lung sounds.
2. The healthcare provider is inspecting the external eye structures of a client. Which finding is a normal racial variation?
- A. Blue sclerae.
- B. Brown macules on the sclerae.
- C. Slightly yellow sclerae in an African-American client.
- D. Conjunctival pallor.
Correct answer: C
Rationale: The slightly yellow color of the sclera is a normal racial variation found in the African-American population. Blue sclerae (Choice A) are associated with osteogenesis imperfecta, not a normal racial variation. Brown macules on the sclerae (Choice B) may indicate issues like melanoma or melanosis but are not a normal racial variation. Conjunctival pallor (Choice D) suggests anemia or decreased blood flow but is not a normal racial variation.
3. During which stage of mitosis does the nuclear envelope begin to disappear and the chromosomes start attaching to the spindle forming along the cell's axis?
- A. Prometaphase
- B. Metaphase
- C. Anaphase
- D. Prophase
Correct answer: A
Rationale: The correct answer is A, Prometaphase. During prometaphase, the nuclear envelope disintegrates, and chromosomes start attaching to spindle fibers. In metaphase, chromosomes align in the middle of the cell. Anaphase is characterized by the separation of sister chromatids, and prophase involves the condensation of chromosomes and the beginning of spindle formation.
4. A client with diabetes mellitus has a blood glucose level of 350 mg/dL. Which of these actions should the nurse take first?
- A. Administer insulin as ordered
- B. Encourage the client to drink fluids
- C. Notify the healthcare provider
- D. Recheck the blood glucose level in 30 minutes
Correct answer: A
Rationale: Administering insulin as ordered is the priority action when a client with diabetes mellitus has a blood glucose level of 350 mg/dL. Insulin helps to lower the high blood glucose level and prevent complications such as diabetic ketoacidosis. Encouraging the client to drink fluids may be beneficial but does not address the immediate need to lower the blood glucose level. Notifying the healthcare provider and rechecking the blood glucose level can be important steps but should come after administering insulin to address the high glucose level promptly.
5. A client with a postoperative wound that eviscerated yesterday has an elevated temperature. What is the most important intervention for the nurse to implement?
- A. Initiate contact isolation.
- B. Obtain a wound swab for culture and sensitivity.
- C. Assess temperature every 4 hours.
- D. Use alcohol-based solutions for hand hygiene.
Correct answer: B
Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.
