Which of the following lab value profiles should the nurse know to be consistent with hemolytic anemia?
- A. Increased RBC, decreased bilirubin, decreased Hgb and Hct, increased reticulocytes
- B. Decreased RBC, increased bilirubin, decreased Hgb and Hct, increased reticulocytes
- C. Decreased RBC, decreased bilirubin, increased Hgb and Hct, decreased reticulocytes
- D. Increased RBC, increased bilirubin, increased Hgb and Hct, decreased reticulocytes
Correct Answer: A
Rationale: Step-by-step rationale for the correct answer (A):
1. Increased RBC: Hemolytic anemia leads to increased RBC production as the body compensates for the destruction of red blood cells.
2. Decreased bilirubin: Bilirubin levels decrease due to the accelerated breakdown of red blood cells.
3. Decreased Hgb and Hct: Hemolysis causes a decrease in hemoglobin and hematocrit levels as red blood cells are destroyed.
4. Increased reticulocytes: Reticulocytes are immature red blood cells released by the bone marrow in response to increased RBC destruction.
Summary:
- Choice B is incorrect as hemolytic anemia would lead to increased, not decreased, bilirubin levels.
- Choice C is incorrect as hemolytic anemia would lead to decreased, not increased, Hgb and Hct levels.
- Choice D is incorrect as hemolytic anemia would not lead to increased levels of all parameters

The nurse is using critical thinking skills during the first phase of the nursing process. Which action indicates the nurse is in the first phase?
- A. Completes a comprehensive database
- B. Identifies pertinent nursing diagnoses
- C. Intervenes based on priorities of patient care
- D. Determines whether outcomes have been achieved
Correct Answer: A
Rationale: The correct answer is A because the first phase of the nursing process is assessment, where the nurse gathers comprehensive data about the patient's health status. This step is crucial in identifying problems and setting priorities for care. Choice B comes in the second phase (diagnosis), C in the third phase (planning), and D in the last phase (evaluation). Assessing the patient's condition is the foundation for the rest of the nursing process.
For a client with sickle cell anemia, how does the nurse assess for jaundice?
- A. The nurse assesses mental status, verbal ability, and motor strength
- B. The nurse observes the joints for signs of swelling
- C. The nurse inspects the skin and sclera for jaundice
- D. The nurse collects a urine specimen
Correct Answer: C
Rationale: The correct answer is C because jaundice is a common manifestation of sickle cell anemia due to the breakdown of red blood cells. The nurse should inspect the skin and sclera for the characteristic yellow discoloration indicating jaundice. This assessment is specific to identifying jaundice, which is directly related to the disease process.
Choice A is incorrect as it relates to assessing neurological function, not jaundice. Choice B is incorrect as joint swelling is not a typical sign of jaundice in sickle cell anemia. Choice D is incorrect as a urine specimen is not used to assess jaundice; skin and sclera inspection are more appropriate.
A client who has been taking prednisone to treat lupus erythematosus has discontinued the medication because of lack of funds to buy the drug. When the nurse becomes aware of the situation, which assessment is most important for the nurse to make first?
- A. breath sounds
- B. blood pressure
- C. capillary refill
- D. butterfly rash
Correct Answer: B
Rationale: Step-by-step rationale for choice B being correct:
1. Blood pressure is vital in this scenario due to prednisone discontinuation.
2. Abruptly stopping prednisone can lead to adrenal insufficiency.
3. Adrenal insufficiency can cause hypotension, a life-threatening condition.
4. Monitoring blood pressure can help detect and manage potential complications.
Summary of other choices:
A: Breath sounds – Important but not the priority in this specific situation.
C: Capillary refill – Useful for assessing circulation but not urgent in this context.
D: Butterfly rash – A characteristic of lupus, but not a critical concern in this scenario.
Which of the following intravenous solutions is hypotonic?
- A. Normal saline
- B. Ringer’s lactate
- C. 0.45% saline
- D. 5% dextrose in normal saline A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET F
Correct Answer: C
Rationale: The correct answer is C: 0.45% saline. This solution is hypotonic because it has a lower osmolarity compared to the intracellular fluid. It contains fewer solutes than the cells, causing water to move into the cells by osmosis, potentially causing them to swell.
Normal saline (A) and Ringer's lactate (B) are isotonic solutions, meaning they have a similar osmolarity to the intracellular fluid and do not cause significant water shifts.
5% dextrose in normal saline (D) is a hypertonic solution, containing more solutes than the cells, leading to water movement out of the cells.
The nurse is developing a teaching plan for a client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus?
- A. antidiuretic hormone (ADH).
- B. follicle-stimulating hormone (FSH).
- C. thyroid-stimulating hormone (TSH).
- D. luteinizing hormone (LH).
Correct Answer: A
Rationale: The correct answer is A: antidiuretic hormone (ADH). In diabetes insipidus, there is a deficiency of ADH, which regulates water balance by reducing urine output. Without ADH, excessive urination and thirst occur. FSH, TSH, and LH are not related to water balance regulation. FSH and LH are involved in reproductive functions, while TSH regulates thyroid hormone production. Therefore, the nurse should focus on educating the client about the importance of ADH in managing diabetes insipidus.
