The presence of anemia is characterized by a/an:
- A. Increase of red blood cells
- B. Increased hemoglobin
- C. Decrease in the concentration of red blood
- D. Decreased blood count cells
Correct Answer: C
Rationale: Step-by-step rationale:
1. Anemia is a condition where there is a decrease in the concentration of red blood cells.
2. Red blood cells carry oxygen to the body's tissues, so a decrease in their concentration leads to reduced oxygen delivery.
3. This decrease in red blood cell concentration can be measured through a decrease in hematocrit levels.
4. Choices A and B are incorrect because anemia involves a decrease, not an increase, in red blood cells and hemoglobin.
5. Choice D is incorrect as it mentions "decreased blood count cells," which is not a specific term related to anemia.
Summary: The correct answer is C because anemia is characterized by a decrease in the concentration of red blood cells, leading to reduced oxygen delivery, while the other choices are incorrect due to inaccuracies in describing anemia.

A patient expresses fear of going home and being alone. Vital signs are stable and the incision is nearly completely healed. What can the nurse infer from the subjective data?
- A. The patient can now perform the dressing changes without help.
- B. The patient can begin retaking all of the previous medications.
- C. The patient is apprehensive about discharge.
- D. The patient’s surgery was not successful.
Correct Answer: C
Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This is supported by stable vital signs and nearly healed incision, suggesting physical recovery. Choice A is incorrect as fear of being alone does not necessarily mean the patient can perform dressing changes independently. Choice B is incorrect as resuming medications is not related to the patient's fear of being alone. Choice D is incorrect as there is no evidence to suggest the surgery was unsuccessful based on the information provided.
What is the focus of a diagnostic statement for a collaborative problem?
- A. The client problem
- B. The potential complication
- C. The nursing diagnosis
- D. The medical diagnosis
Correct Answer: B
Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying potential complications that may arise due to the client's health issue. This is important for developing effective interventions to prevent or manage these complications. Choice A focuses on the client's problem itself, not on potential complications. Choice C is related to nursing diagnosis, not collaborative problems. Choice D refers to medical diagnosis, which is different from collaborative problems involving nursing and other healthcare disciplines. Therefore, B is the correct focus for a diagnostic statement in a collaborative problem scenario.
When the LPN is assisting the patient to use an incentive spirometer, which of the following actions by the patient indicates that the patient needs further teaching on how to use the spirometer?
- A. Taking two normal breaths before use.
- B. Sitting upright before use.
- C. Inhaling deeply to reach target.
- D. Exhaling deeply to reach target.
Correct Answer: D
Rationale: The correct answer is D because exhaling deeply before using the spirometer is incorrect. The purpose of the incentive spirometer is to encourage deep inhalation to improve lung function. Exhaling deeply before using the spirometer goes against this goal and may hinder the effectiveness of the device. Choices A, B, and C are all correct actions when using the spirometer. Taking two normal breaths helps to prepare the lungs, sitting upright optimizes lung expansion, and inhaling deeply to reach the target helps to improve lung ventilation.
Mrs. Santos, a 75-year old patient with type II diabetes is in emergency department with signs of hyperglycemic, hyperosmolar nonketotic (HHNK) coma. What assessment finding should the nurse expect?
- A. Fruity odor of the breath
- B. shallow, deep respirations
- C. severe dehydration
- D. profuse sweating
Correct Answer: C
Rationale: The correct answer is C: severe dehydration. In HHNK coma, the body tries to eliminate excess glucose through frequent urination, leading to dehydration. This results in decreased blood volume, causing hypotension and tachycardia. Signs include dry mucous membranes, poor skin turgor, and concentrated urine output. Fruity odor of the breath (A) is associated with diabetic ketoacidosis, not HHNK coma. Shallow, deep respirations (B) and profuse sweating (D) are not typically associated with HHNK coma.
Blood and fluid loss from frequent diarrhea may cause hypovolemia and you can quickly assess volume depletion in Miss CC by:
- A. Measuring the quantity and specific gravity of her urine output
- B. Taking her blood pressure
- C. Comparing the patient’s present weight with her last weight
- D. Administering the oral water test
Correct Answer: C
Rationale: The correct answer is C: Comparing the patient’s present weight with her last weight. This is the most direct and reliable method to assess volume depletion due to fluid loss. By comparing the patient's current weight with her last weight, you can easily determine if there has been a significant decrease in weight indicating fluid loss and potential hypovolemia.
Explanation of why other choices are incorrect:
A: Measuring the quantity and specific gravity of her urine output - This method may provide some information about hydration status, but it is not as direct or reliable as comparing weight changes.
B: Taking her blood pressure - While blood pressure can indicate hypovolemia, it may not provide immediate insight into volume depletion caused by diarrhea.
D: Administering the oral water test - This test is not commonly used to assess volume depletion and may not be as effective or quick as comparing weight changes.
