1. A 57-year-old male presents to his primary care provider with a red face, hands, feet, ears, headache, and drowsiness. A blood smear reveals an increased number of erythrocytes, indicating:
- A. Leukemia
- B. Sideroblastic anemia
- C. Hemosiderosis
- D. Polycythemia vera
Correct answer: D
Rationale: In this case, the symptoms of a red face, hands, feet, ears, headache, and drowsiness along with an increased number of erythrocytes in the blood smear are indicative of polycythemia vera. This condition is characterized by the overproduction of red blood cells, leading to symptoms related to increased blood volume and viscosity. Leukemia (Choice A) is a cancer of the blood and bone marrow, but the presentation described here is more suggestive of polycythemia vera. Sideroblastic anemia (Choice B) is characterized by abnormal iron deposits in erythroblasts, not an increased number of erythrocytes. Hemosiderosis (Choice C) refers to abnormal accumulation of iron in the body, not an increase in red blood cells as seen in polycythemia vera.
2. After experiencing several months of worsening nocturia, a patient has been assessed for benign prostatic hypertrophy (BPH) and has begun drug treatment. In addition to nocturia, what other sign or symptom is most likely to accompany BPH?
- A. Hematuria
- B. Erectile dysfunction
- C. Urinary frequency
- D. Flank pain
Correct answer: A
Rationale: The correct answer is hematuria. Hematuria, which is the presence of blood in the urine, is a common sign associated with benign prostatic hypertrophy (BPH). It can occur due to irritation or damage to the prostate tissue. While urinary frequency and erectile dysfunction can also be seen in BPH patients, hematuria is more specifically linked to prostate issues. Flank pain is not typically a direct symptom of BPH.
3. If the client's dorsal columns are not functioning, the nurse will observe which response during neuro testing, where the nurse asks the client to close his eyes and then proceeds to touch corresponding parts of the body on each side simultaneously with two sharp points?
- A. The client will not be able to distinguish between the two points.
- B. The client will feel only one point of contact.
- C. The client will accurately identify both points.
- D. The client will report no sensation in the touched areas.
Correct answer: A
Rationale: If the client's dorsal columns are not functioning, the ability to distinguish between two closely spaced points is impaired. This results in the client not being able to differentiate between the two points when touched simultaneously. Choice B is incorrect because the client feeling only one point suggests an intact dorsal column function. Choice C is incorrect as accurately identifying both points indicates normal discrimination ability. Choice D is incorrect as reporting no sensation does not correspond to the specific impairment related to dorsal column dysfunction.
4. During a home visit to a family of three: a mother, father, and their child, the mother tells the community nurse that the father (who is not present) had hit the child on several occasions when he was drinking. The mother further explains that she has talked her husband into going to Alcoholics Anonymous and asks the nurse not to interfere so her husband won’t get angry and refuse treatment. Which of the following is the best response of the nurse?
- A. The nurse agrees not to interfere if the husband attends an Alcoholics Anonymous meeting that evening.
- B. The nurse commends the mother’s efforts and agrees to let her handle things.
- C. The nurse commends the mother’s efforts and also contacts protective services.
- D. The nurse confronts the mother’s failure to protect the child.
Correct answer: C
Rationale: In this situation, the best response for the nurse is to commend the mother's efforts in seeking help for her husband by encouraging him to attend Alcoholics Anonymous. However, it is crucial for the nurse to also contact protective services to ensure the safety and well-being of the child. Option A is incorrect as it is not appropriate to condition non-interference on the husband attending a meeting that evening. Option B is incorrect because solely letting the mother handle things might put the child at risk. Option D is incorrect as it does not address the immediate need to ensure the child's safety through involving protective services.
5. When educating a client about to undergo a pacemaker insertion, the nurse explains the normal phases of cardiac muscle tissue. During the repolarization phase, the nurse will stress that membranes must be repolarized before they can be re-excited. Within the cell, the nurse understands that:
- A. Potassium channels open while sodium channels close, causing repolarization to the resting state.
- B. The influx of calcium is the primary stimulus for the repolarization of cardiac tissue.
- C. Only the electrical activity within the heart will determine when repolarization occurs.
- D. The cell membranes need to stay calm, resulting in muscle tissue becoming refractory.
Correct answer: A
Rationale: During the repolarization phase of cardiac muscle tissue, potassium channels open while sodium channels close. This process is crucial for the cardiac muscle to return to its resting state after depolarization. Potassium moving out of the cell and sodium staying out helps reset the membrane potential and prepare the cell for the next depolarization phase. The influx of calcium is not the primary stimulus for repolarization in cardiac tissue; it is mainly involved in the depolarization phase. While electrical activity within the heart influences repolarization, the specific ion movements described in choice A are what physiologically drive repolarization. Cell membranes need to be in an active state during repolarization, not calm, to facilitate the necessary ion movements for muscle tissue to properly function.
