Theories of Health Behavior Change Questions
Question 1 of 5
When evaluating an arterial blood gas from a male client with a subdural hematoma, the nurse notes the Paco2 is 30 mm Hg. Which of the following responses best describes the result?
Correct Answer: A
Rationale: Rationale: - Correct answer (A): Paco2 of 30 mm Hg is appropriate because lowering CO2 helps reduce ICP in clients with subdural hematoma. - Incorrect answer (B): Paco2 is not indicative of oxygenation status; it measures CO2 levels. - Incorrect answer (C): Paco2 of 30 mm Hg is low, not normal. - Incorrect answer (D): Paco2 of 30 mm Hg indicates hyperventilation, not hypoventilation.
Question 2 of 5
Cleo is diagnosed with osteoporosis. Which electrolytes are involved in the development of this disorder?
Correct Answer: B
Rationale: The correct answer is B: Calcium and phosphorous. Osteoporosis is a condition characterized by weak and brittle bones. Calcium and phosphorous are essential minerals for bone health and strength. Calcium is a major component of bone tissue, while phosphorous plays a key role in bone mineralization. A deficiency in either of these electrolytes can lead to decreased bone density and increased risk of fractures. Sodium, potassium, and other electrolytes do not directly contribute to bone health in the same way that calcium and phosphorous do. Therefore, choices A, C, and D are incorrect as they do not involve the electrolytes crucial for bone health.
Question 3 of 5
Nurse Michelle calculates the IV flow rate for a postoperative client. The client receives 3,000 ml of Ringer's lactate solution IV to run over 24 hours. The IV infusion set has a drop factor of 10 drops per milliliter. The nurse should regulate the client's IV to deliver how many drops per minute?
Correct Answer: B
Rationale: To calculate the IV flow rate in drops per minute, we use the formula: (Drop factor x Volume to be infused in ml) / Time in minutes Given drop factor of 10, 3,000 ml to be infused over 24 hours (1,440 minutes), we get: (10 drops/ml x 3,000 ml) / 1,440 minutes = 21 drops/minute (Answer B). Choice A (18) is incorrect as it does not consider the correct drop factor and volume. Choice C (35) and D (40) are incorrect as they result from incorrect calculations.
Question 4 of 5
Mario comes to the clinic complaining of fever, drenching night sweats, and unexplained weight loss over the past 3 months. Physical examination reveals a single enlarged supraclavicular lymph node. Which of the following is the most probable diagnosis?
Correct Answer: D
Rationale: The most probable diagnosis for Mario is Hodgkin's disease. This is supported by his symptoms of fever, night sweats, weight loss, and an enlarged supraclavicular lymph node, which are classic signs of Hodgkin's lymphoma. The presence of a single enlarged supraclavicular lymph node is particularly concerning for malignancy. Influenza (choice A) typically presents with respiratory symptoms, not persistent lymphadenopathy. Sickle cell anemia (choice B) is a genetic disorder affecting red blood cells, not associated with the symptoms described. Leukemia (choice C) may present with similar symptoms but typically involves multiple lymph nodes, not a single enlarged node. Therefore, the correct answer is D, Hodgkin's disease.
Question 5 of 5
Timothy's arterial blood gas (ABG) results are as follows; pH 7.16; Paco2 80 mm Hg; Pao2 46 mm Hg; HCO3- 24mEq/L; Sao2 81%. This ABG result represents which of the following conditions?
Correct Answer: C
Rationale: The correct answer is C, respiratory acidosis. The low pH (7.16) indicates acidosis, and the high Paco2 (80 mm Hg) suggests respiratory involvement. The Pao2 (46 mm Hg) is low, indicating hypoxemia. The HCO3- (24 mEq/L) is normal, ruling out metabolic acidosis. The Sao2 (81%) is also low, supporting respiratory acidosis due to poor oxygen exchange in the lungs. A: Metabolic acidosis - ruled out due to normal HCO3- B: Metabolic alkalosis - ruled out due to low pH and normal HCO3- D: Respiratory alkalosis - ruled out due to high Paco2 and low Pao2
