If a patient has elevated pulmonary vascular pressures, the nurse understands that the patient is most likely to develop which of the ff. physiological cardiac changes?
- A. Left atrial atrophy
- B. Left ventricular hypertrophy
- C. Right atrial atrophy
- D. Right ventricular hypertrophy
Correct Answer: D
Rationale: Elevated pulmonary vascular pressures can lead to pulmonary hypertension, which causes increased pressure in the right side of the heart. The right ventricle has to work harder to pump blood against the increased resistance in the pulmonary circulation. Over time, this can result in the development of right ventricular hypertrophy as the muscle of the right ventricle thickens in response to the increased workload. This is a compensatory mechanism to try to maintain cardiac output despite the increased pressure in the pulmonary circulation. Left atrial atrophy, left ventricular hypertrophy, and right atrial atrophy are not typically associated with elevated pulmonary vascular pressures.

For a client diagnosed with idiopathic thrombocytopenic purpura (ITP), which nursing intervention is appropriate?
- A. Teaching coughing and deep-breathing techniques to help prevent infection
- B. Administering platelets, as ordered to maintain an adequate platelet count
- C. Giving aspirin, as prescribed to control body temperature
- D. Administering stool softeners, as ordered, to prevent straining during infection
Correct Answer: B
Rationale: The appropriate nursing intervention for a client diagnosed with idiopathic thrombocytopenic purpura (ITP) is administering platelets, as ordered, to maintain an adequate platelet count. ITP is a condition characterized by a decrease in platelet count, which can lead to thrombocytopenia and an increased risk of bleeding. Administering platelets can help prevent excessive bleeding and maintain hemostasis in these patients. Platelet transfusions may be required in severe cases to raise the platelet count to a safe level and prevent bleeding complications. It is crucial for nurses to monitor the platelet count regularly and administer platelets as prescribed to manage ITP effectively.
Primary amenorrhea should be considered for any female adolescent who has not reached menarche by
- A. 13 years or has not done so within 3 years of thelarche
- B. 14 years or has not done so within 2 years of thelarche
- C. 14 years or has not done so within 3 years of thelarche
- D. 15 years or has not done so within 3 years of thelarche
Correct Answer: D
Rationale: Primary amenorrhea is suspected if menarche has not occurred by age 15 or within 3 years of thelarche.
A male client, age 45, undergoes a lumbar puncture in which CSF was extracted for a particular neurologic diagnostic procedure. After the procedure, he complains of dizziness and a slight headache. Which of the ff steps must the nurse take to provide comfort to the client? Choose all that apply
- A. Position the client flat for at least 3 hrs or as directed by the physician
- B. Encourage a liberal fluid intake
- C. Keep the room well lit and play some soothing music in the ground
- D. Help the client ambulate and perform a few light leg exercises#
Correct Answer: B
Rationale: - **Encourage a liberal fluid intake (B):** It is essential to maintain hydration after a lumbar puncture to help prevent or alleviate a headache, which may occur due to a decrease in cerebrospinal fluid (CSF) pressure. Adequate hydration can help reduce the chances of a post-lumbar puncture headache.
Which nursing diagnosis is most appropriate for a client with Addison's disease?
- A. Risk for infection
- B. Urinary retention
- C. Excessive fluid volume
- D. Hypothermia
Correct Answer: C
Rationale: Addison's disease is a condition characterized by adrenal insufficiency, resulting in a deficiency of aldosterone and cortisol. Without aldosterone, the body is unable to regulate fluid and electrolyte balance properly, leading to sodium loss and potassium retention. This imbalance can result in excessive fluid volume, as the kidneys retain water and sodium. Symptoms of excessive fluid volume in Addison's disease can include edema, weight gain, and hypertension. Therefore, the most appropriate nursing diagnosis for a client with Addison's disease would be Excessive Fluid Volume.
The nurse is caring for a very low birth weight (VLBW) newborn with a peripheral intravenous infusion. Which statement describes nursing considerations regarding infiltration?
- A. Infiltration occurs infrequently because VLBW newborns are inactive.
- B. Continuous infusion pumps stop automatically when infiltration occurs.
- C. Hypertonic solutions can cause severe tissue damage if infiltration occurs.
- D. Infusion site should be checked for infiltration at least once per 8-hour shift.
Correct Answer: C
Rationale: Infiltration of intravenous fluids in VLBW newborns can lead to serious complications, especially if hypertonic solutions are being administered. Hypertonic solutions have a higher osmolarity than the body's fluids, which can cause severe tissue damage if there is infiltration. It is crucial for the nurse to monitor the infusion site closely for signs of infiltration and take prompt action to prevent further harm to the newborn's delicate skin and tissues. The other options are not directly related to the risk and consequences of infiltration in VLBW newborns.
