Which of the following are signs and symptoms of myocardial infarction?
- A. Persistent chest pain which may radiate to the arm
- B. Brief sternal chest pain on inspiration
- C. Rapid respirations with left-sided weakness and numbness
- D. Left upper quadrant abdominal pain which radiates to the back and shoulder
Correct Answer: A
Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.

A client presents to the emergency department with lower right quadrant abdominal pain, fever, nausea, and occasional diarrhea. After palpating the abdomen, the client displays tenderness. What would the nurse anticipate the client to be experiencing?
- A. Pseudomembranous colitis
- B. Peptic ulcer disease
- C. Appendicitis
- D. Esophageal cancer
Correct Answer: C
Rationale: The correct answer is C: Appendicitis. The symptoms described - lower right quadrant abdominal pain, fever, nausea, diarrhea, and tenderness upon palpation - are classic signs of appendicitis. Appendicitis is an inflammatory condition of the appendix that often presents with these symptoms and requires immediate medical attention. Choice A, Pseudomembranous colitis, typically presents with watery diarrhea and is associated with antibiotic use. Choice B, Peptic ulcer disease, commonly presents with epigastric pain related to meals and can be accompanied by nausea or vomiting, but it does not typically cause right lower quadrant pain. Choice D, Esophageal cancer, usually presents with symptoms related to swallowing difficulties, weight loss, and sometimes chest pain, but it is not associated with the symptoms described in the scenario.
Which of the following would the nurse see in a client with thrombocytopenia?
- A. A decreased platelet cell count
- B. Decreased white blood cell count
- C. Increased red blood cell count
- D. An increased platelet cell count
Correct Answer: A
Rationale: Thrombocytopenia is characterized by a decreased platelet cell count, leading to an increased risk of bleeding. Therefore, the correct answer is A. Choice B, a decreased white blood cell count, is not typically associated with thrombocytopenia. Choice C, an increased red blood cell count, is not a characteristic finding in thrombocytopenia. Choice D, an increased platelet cell count, is the opposite of what is observed in thrombocytopenia.
What causes osteoporosis?
- A. Poor nutrition in infancy
- B. Regularly weight-bearing exercise
- C. Bone loss, frequently during aging
- D. Cerebral palsy and associated disorders
Correct Answer: C
Rationale: The correct answer is C. Osteoporosis is commonly caused by bone loss that occurs with aging, leading to brittle bones. Choice A, poor nutrition in infancy, is not a direct cause of osteoporosis. Choice B, regularly weight-bearing exercise, actually helps in maintaining bone density and strength, reducing the risk of osteoporosis. Choice D, cerebral palsy and associated disorders, is not a common cause of osteoporosis.
Which of the following imbalances is found in clients with syndrome of inappropriate antidiuretic hormone (SIADH)?
- A. Decreased insulin production
- B. Decreased antidiuretic hormone (ADH) production
- C. Increased secretion of antidiuretic hormone (ADH)
- D. Increased production of insulin
Correct Answer: C
Rationale: The correct answer is C: Increased secretion of antidiuretic hormone (ADH). Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of ADH, which leads to water retention and dilution of blood sodium levels. Choices A, B, and D are incorrect because SIADH is not associated with decreased insulin production, decreased ADH production, or increased production of insulin.
Which of the following describes the condition in the body of clients experiencing hypovolemia?
- A. Increased urine retention
- B. Insufficient circulating blood volume
- C. Bounding peripheral pulses
- D. Crackles auscultated in the lungs
Correct Answer: B
Rationale: The correct answer is B: Insufficient circulating blood volume. Hypovolemia is a condition characterized by a decrease in the volume of blood plasma. This reduction in circulating blood volume can lead to inadequate perfusion of tissues and organs, potentially resulting in shock if left untreated. Choices A, C, and D are incorrect because increased urine retention, bounding peripheral pulses, and crackles auscultated in the lungs are not typical manifestations of hypovolemia.
