Adult Health Exam 1

Correct Answer: A

Rationale: The correct answer is A: Autonomy vs. Shame and Doubt. In Erikson's theory, toddlers aged 1-3 years are in the Autonomy vs. Shame and Doubt stage. During this stage, children begin to assert their independence and control over their environment. The behavior of the hospitalized toddler holding a toy and saying 'Mine' demonstrates the child's developing sense of autonomy and ownership. Choices B, C, and D correspond to different stages in Erikson's theory: Industry vs. Inferiority (school-age children), Initiative vs. Guilt (preschoolers), and Trust vs. Mistrust (infants), respectively, which are not applicable to the behavior described.

Correct Answer: A

Rationale: The correct answer is A: Conversion of irregular heart rate to regular heart rhythm. Amiodarone is a medication commonly used to restore and maintain normal heart rhythm in clients with atrial fibrillation. It works by slowing down the electrical signals in the heart, helping to regulate the heartbeat. Choices B, C, and D are incorrect because they do not directly relate to the therapeutic response expected from administering amiodarone in a client with atrial fibrillation. Pulse oximetry readings, peripheral pulses, capillary refill, and exercise tolerance are important assessments but are not the primary therapeutic goal of using amiodarone in this situation.

Correct Answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.

Correct Answer: C

Rationale: When a client presents with new-onset tachycardia, the first action the nurse should take is to assess for any associated symptoms like chest pain or discomfort. This is important to differentiate the potential causes of tachycardia and guide appropriate interventions. Checking the client's temperature (Choice A) may be relevant in certain situations but is not the priority when tachycardia is observed. Administering prescribed beta-blockers (Choice B) should only be done after a comprehensive assessment and healthcare provider's orders. Monitoring the client's blood pressure (Choice D) is important, but assessing for chest pain or discomfort takes precedence in this scenario to rule out cardiac causes of tachycardia.

Correct Answer: A

Rationale: The most important assessment to perform when caring for a client with a tracheostomy is to check the client's oxygen saturation. This assessment is crucial as it ensures that the client is receiving adequate oxygen through the tracheostomy. Monitoring oxygen saturation provides immediate information on the client's respiratory status and the effectiveness of the airway management. Assessing the tracheostomy site for signs of infection is important but not as critical as ensuring adequate oxygenation. Monitoring the respiratory rate is also essential but does not directly assess the effectiveness of oxygenation. Ensuring tracheostomy ties are secure is important for maintaining the device but does not directly evaluate the client's oxygenation status.
