Theories of Health Behavior Change Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
Situation: A nurse may encounter children with mental disorders. Her knowledge of these various disorders is vital. When planning school interventions for a child with a diagnosis of attention deficit hyperactivity disorder, a guide to remember is to:
Correct Answer: A
Rationale: Rationale for Choice A (Correct Answer): - Children with ADHD benefit from structure to help them stay organized and focused. - Providing a structured environment helps them understand expectations and routines. - Structure can also help in managing impulsivity and improving behavior. Summary of Other Choices: - Choice B (Ignore overactivity) is incorrect as ignoring the behavior can lead to further issues and does not address the underlying need for structure. - Choice C (Encourage play to dissipate energy) may not address the core issues of ADHD related to organization and focus. - Choice D (Remove child from classroom) does not provide a proactive approach to managing ADHD and may not teach the child appropriate coping strategies.
