Theories of Health Behavior Change Questions
Question 1 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 2 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 3 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
Question 4 of 5
The nurse is aware that the following terms used to describe reduced cardiac output and perfusion impairment due to ineffective pumping of the heart is:
Correct Answer: B
Rationale: Step-by-step rationale for choice B (Cardiogenic shock) as the correct answer: 1. Cardiogenic shock refers to reduced cardiac output and perfusion impairment due to ineffective pumping of the heart. 2. In cardiogenic shock, the heart's ability to pump blood is compromised, leading to decreased circulation and inadequate perfusion. 3. Anaphylactic shock (choice A) is a severe allergic reaction, not related to cardiac function. 4. Distributive shock (choice C) involves widespread vasodilation and impaired blood flow regulation, not solely related to ineffective heart pumping. 5. Myocardial infarction (MI) (choice D) is a heart attack resulting from blocked blood flow to the heart, not directly related to reduced cardiac output.
Question 5 of 5
The wife admits that she is a victim of abuse and opens up about her persistent distaste for sex. This sexual disorder is:
Correct Answer: A
Rationale: The correct answer is A: Sexual desire disorder. The wife's persistent distaste for sex indicates a lack of interest or desire for sexual activity, which aligns with the symptoms of Sexual Desire Disorder. This disorder is characterized by a persistent or recurrent lack of sexual fantasies and desire for sexual activity, causing distress or interpersonal difficulties. The other choices (B, C, D) do not fully capture the wife's situation as they focus on different aspects of sexual dysfunction such as arousal, orgasm, and pain, which are not explicitly mentioned in the scenario provided.
