Choose the condition that exhibits blood values with a low pH and a high PCO :
- A. Respiratory acidosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Metaboli₂c alkalosis
Correct Answer: A
Rationale: Correct Answer: A: Respiratory acidosis
Rationale:
1. Respiratory acidosis is caused by inadequate ventilation leading to increased PCO₂ and decreased pH.
2. Low pH indicates acidosis, and high PCO₂ indicates respiratory component.
3. Metabolic acidosis (B) results from non-respiratory causes.
4. Respiratory alkalosis (C) is characterized by high pH and low PCO₂.
5. Metabolic alkalosis (D) is caused by non-respiratory factors with high pH.

The nurse is gathering data on a patient. Which data will the nurse report as objective data?
- A. States “doesn’t feel good”
- B. Reports a headache
- C. Respirations 16
- D. Nauseated
Correct Answer: C
Rationale: The correct answer is C because respirations of 16 are measurable and quantifiable, making them objective data. Subjective data, like choices A, B, and D, are based on the patient's feelings or experiences and cannot be measured or observed directly. Choice A is subjective as it relies on the patient's self-report. Choice B is subjective as it describes a symptom reported by the patient. Choice D is subjective as it reflects the patient's feeling of nausea. Objective data is essential for making accurate clinical assessments and decisions.
For a client with polycythemia vera, how can the nurse help decrease the risk for thrombus formation?
- A. Teach the client how to perform isometric exercises
- B. Help the client don thromboembolic stocking or support hose during waking hours
- C. Advise drinking 3 quarts (L) of fluid per day
- D. Instruct the client to rest immediately if chest pain develops A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET I THE HEMATOLOGIC SYSTEM
Correct Answer: B
Rationale: The correct answer is B: Help the client don thromboembolic stocking or support hose during waking hours. This intervention helps decrease the risk for thrombus formation in polycythemia vera by promoting venous return and preventing blood pooling in the lower extremities. Compression stockings improve circulation and reduce the risk of blood clots. Isometric exercises (choice A) may increase blood pressure and heart rate, potentially worsening the risk of thrombus formation. Drinking excess fluid (choice C) can lead to hypervolemia and increase the risk of clotting. Resting immediately if chest pain develops (choice D) is important but does not directly address the prevention of thrombus formation in polycythemia vera.
Which nursing actions will the nurse perform in the evaluation phase of the nursing process? (Select all that apply.)
- A. Set priorities for patient care.
- B. Determine whether outcomes or standards are met.
- C. Ambulate patient 25 feet in the hallway.
- D. Document results of goal achievement.
Correct Answer: A
Rationale: In the evaluation phase of the nursing process, the nurse sets priorities for patient care to determine the effectiveness of nursing interventions. This involves comparing achieved outcomes with established goals. Choices B and D are related to evaluation as they involve determining whether outcomes or standards are met and documenting results of goal achievement, respectively. However, choice C, ambulating the patient, is an intervention that would typically occur in the implementation phase, not the evaluation phase. Therefore, the correct answer is A because setting priorities for patient care is a key component of the evaluation phase.
The client is suspected of having myasthenia gravis. Edrophonium (Tensilon) 2 mg is administered intravenously to determine the diagnosis. Which of the following indicates that the client has myasthenia gravis?
- A. Joint pain following administration of the medication
- B. Feelings of faintness, dizziness, hypotension, and signs of flushing in the client
- C. A decrease in muscle strength within 30 to 60 seconds following administration of the medication.
- D. An increase in muscle strength within 30 to 60 seconds following administration of the medication
Correct Answer: C
Rationale: The correct answer is C because in myasthenia gravis, which is characterized by muscle weakness and fatigue, the administration of edrophonium will temporarily improve muscle strength due to increased availability of acetylcholine at the neuromuscular junction. This improvement should be noted within 30 to 60 seconds after the administration of the medication.
Choice A is incorrect because joint pain is not a typical response to edrophonium in the context of myasthenia gravis.
Choice B is incorrect because feelings of faintness, dizziness, hypotension, and flushing are more indicative of a cholinergic crisis, which occurs when too much edrophonium is administered.
Choice D is incorrect because an increase in muscle strength post-edrophonium administration would not be expected in a client with myasthenia gravis.
In a 28-year-old female client who is being successfully treated for Cushing syndrome, the nurse would expect a decline in:
- A. serum glucose level.
- B. bone mineralization.
- C. hair loss
- D. menstrual flow.
Correct Answer: D
Rationale: The correct answer is D: menstrual flow. In a 28-year-old female with Cushing syndrome, excess cortisol levels can disrupt the menstrual cycle, leading to irregular or absent periods. Successful treatment for Cushing syndrome aims to restore normal cortisol levels, which should result in the resumption of regular menstrual flow. This indicates that the hormonal balance is improving.
Now, let's analyze the other choices:
A: Serum glucose level - While Cushing syndrome can lead to hyperglycemia, successful treatment would aim to normalize glucose levels, not cause a decline.
B: Bone mineralization - Cushing syndrome can cause osteoporosis due to loss of bone density, but successful treatment would help prevent further bone loss rather than decline.
C: Hair loss - Cushing syndrome can cause hair loss, but successful treatment would not necessarily lead to a decline in hair loss as it may take time for hair to regrow.
Therefore, the correct answer is D as it directly relates to the restoration of hormonal
