how does shock usually progress

Exam Cram NCLEX RN Practice Questions

1. How does shock typically progress?

A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

2. Which clinical manifestations are recognized in nephrotic syndrome?

A. Hematuria, bacteriuria, weight gain
B. Gross hematuria, albuminuria, fever
C. Hypertension, weight loss, proteinuria
D. Massive proteinuria, hypoalbuminemia, edema

Correct answer: D

Rationale: Nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema. In this syndrome, there is loss of proteins, particularly albumin, in the urine leading to hypoalbuminemia, fluid retention, and subsequent edema. This results in elevated lipid levels like hypercholesterolemia, but not hypertension. Therefore, choices A, B, and C are incorrect. Hematuria, bacteriuria, fever, and weight loss are not typically associated with nephrotic syndrome, distinguishing it from other kidney disorders.

3. A client is admitted to the emergency room with renal calculi and is complaining of moderate to severe flank pain and nausea. The client's temperature is 100.8 degrees Fahrenheit. The priority nursing goal for this client is:

A. Maintain fluid and electrolyte balance
B. Control nausea
C. Manage pain
D. Prevent urinary tract infection

Correct answer: C

Rationale: In the scenario presented, the priority nursing goal for a client with renal calculi experiencing moderate to severe flank pain and nausea should be to manage pain. Pain management is crucial as it alleviates suffering, improves comfort, and enhances the quality of life for the client. In the case of ureteral colic from renal calculi, the cornerstone of management is effective pain control. Prompt analgesia, typically achieved with parenteral narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs), is essential to provide relief and facilitate the passage of the calculi. While maintaining fluid and electrolyte balance is important in clients with renal calculi, addressing pain takes precedence as it directly impacts the client's immediate well-being. Controlling nausea and preventing urinary tract infections are also important aspects of care, but they are secondary to managing the primary concern of pain in this urgent situation.

4. An 85-year-old male has been losing mobility and gaining weight over the last two months. The patient also has the heater running in his house 24 hours a day, even on warm days. Which of the following tests is most likely to be performed?

A. CBC (complete blood count)
B. ECG (electrocardiogram)
C. Thyroid function tests
D. CT scan

Correct answer: C

Rationale: The symptoms of weight gain and poor temperature tolerance in an elderly male suggest a potential thyroid dysfunction. Thyroid function tests are crucial in differentiating between hyperthyroidism, hypothyroidism, and a euthyroid state. These tests involve measuring the serum levels of thyroid hormones T3 and T4, also known as thyroxine, to evaluate thyroid function accurately. A complete blood count (Choice A) would not directly address the symptoms presented. An electrocardiogram (Choice B) assesses heart activity and would not be the primary test for these symptoms. A CT scan (Choice D) provides detailed images of internal organs and structures, which would not be the initial investigation for the described symptoms.

5. A patient is admitted to the emergency department with an open stab wound to the left chest. What is the first action that the nurse should take?

A. Position the patient so that the left chest is dependent
B. Tape a nonporous dressing on three sides over the chest wound
C. Cover the sucking chest wound firmly with an occlusive dressing
D. Keep the head of the patient's bed at no more than 30 degrees elevation

Correct answer: B

Rationale: The correct initial action for a patient with an open stab wound to the chest is to tape a nonporous dressing on three sides over the chest wound. This dressing technique allows air to escape during expiration but prevents air from entering the pleural space during inspiration, helping to prevent tension pneumothorax. Placing the patient so that the left chest is dependent or covering the wound with an occlusive dressing can trap air in the pleural space, leading to tension pneumothorax. Keeping the head of the bed elevated at 30 to 45 degrees helps facilitate breathing and is not the first action to take when managing an open chest wound.
