CAT Exam Practice
1. Prior to surgery, written consent must be obtained. What is the nurse’s legal responsibility with regard to obtaining written consent?
- A. Validate the client's understanding of the surgical procedure to be conducted
- B. Explain the surgical procedure to the client and ensure the client comprehends before signing the consent form
- C. Ensure the client, not a family member, signs the surgical consent form
- D. Confirm that the surgical consent form is signed and included in the client's record
Correct answer: A
Rationale: The nurse's legal responsibility in obtaining written consent is to validate the client's understanding of the surgical procedure to be conducted. This process ensures that the client has been comprehensively informed about the procedure, including its risks, benefits, and alternatives. Choice B is incorrect because it does not emphasize the validation of client understanding, which is crucial for informed consent. Choice C is incorrect as the client, not a family member, should provide consent unless specific circumstances dictate otherwise. Choice D is incorrect because although ensuring the consent form is signed and filed is important, it does not address the primary responsibility of confirming the client's comprehension and ensuring informed consent.
2. A client with obsessive-compulsive disorder (OCD) repeatedly checks the locks on the doors. What is the most therapeutic nursing intervention?
- A. Allow the client to continue the behavior to reduce anxiety.
- B. Encourage the client to discuss the thoughts and feelings behind the behavior.
- C. Restrict the client's access to the locks.
- D. Schedule specific times for the client to check the locks.
Correct answer: B
Rationale: The most therapeutic nursing intervention for a client with obsessive-compulsive disorder (OCD) who repeatedly checks locks is to encourage the client to discuss the thoughts and feelings behind the behavior. By exploring the underlying anxiety and triggers, the client can work towards understanding and managing their compulsions. Choice A is incorrect because allowing the client to continue the behavior does not address the root cause or help modify the behavior. Choice C is inappropriate as restricting access to locks can increase anxiety and worsen symptoms. Choice D of scheduling specific times for checking locks does not address the underlying psychological issues driving the behavior.
3. A client with a history of myocardial infarction (MI) is receiving a beta-blocker medication. What is the most important outcome for the nurse to monitor?
- A. Heart rate and blood pressure
- B. Blood glucose levels
- C. Respiratory rate
- D. Liver function tests
Correct answer: A
Rationale: The correct answer is A: Heart rate and blood pressure. When a client with a history of myocardial infarction (MI) is on a beta-blocker medication, monitoring heart rate and blood pressure is crucial. Beta-blockers lower heart rate and blood pressure, so monitoring these parameters helps assess the medication's effectiveness and prevent complications like bradycardia or hypotension. Choices B, C, and D are not the most important outcomes to monitor in this scenario. Blood glucose levels are typically monitored in clients with diabetes or when using medications that affect glucose levels. Respiratory rate is important in assessing respiratory function and oxygenation, while liver function tests are more relevant when monitoring the impact of medications on liver health.
4. A parent is reviewing safety measures for an 8-month-old infant with a nurse. Which of the following statements by the parent indicates an understanding of safety for the infant?
- A. “My baby loved to play with the crib gym, but I took it out of the crib.”
- B. “I just bought a firm mattress so my baby will sleep better.”
- C. “My baby really likes sleeping on the fluffy pillow we just got.”
- D. “I put the baby’s car seat on the table after I put him in it.”
Correct answer: A
Rationale: Choice A is correct because removing the crib gym prevents potential safety hazards such as choking or entrapment. Choices B, C, and D are incorrect as they pose risks to the infant's safety. A firm mattress is recommended for infants to reduce the risk of suffocation. Soft mattresses and fluffy pillows increase the risk of suffocation and Sudden Infant Death Syndrome (SIDS). Placing the baby's car seat on a table can lead to falls or other accidents.
5. As a community health nurse covering a cluster of Barangays, your population coverage includes the following:
- A. Families in their homes, School population, Workers in factories
- B. Families in their homes, School population, Patients in hospital
- C. All except workers in factories
- D. All except patients in hospital
Correct answer: A
Rationale: The correct answer is A: 'Families in their homes, School population, Workers in factories.' As a community health nurse, you are responsible for providing healthcare services and promoting health within the community. This includes visiting families in their homes to assess their health needs, working with the school population to educate them on preventive health measures, and ensuring the health and safety of workers in factories. Choices B, C, and D are incorrect because they do not encompass the full scope of a community health nurse's responsibilities. Choice B does not include workers in factories, Choice C excludes an important population group, and Choice D excludes an essential setting where healthcare services are provided.
