What is the first exercise that should be performed by a client who had a mastectomy?

Correct Answer: D

Rationale: The correct answer is D: Squeezing a ball. The first exercise that should be done by a client with a mastectomy is squeezing a ball. This helps in regaining strength and mobility in the affected area. Choices A, B, and C are incorrect as they are not typically the initial exercises recommended post-mastectomy. Walking the hand up the wall, sweeping the floor, and combing hair are activities that may be introduced later in the rehabilitation process.

Correct Answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

Correct Answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

Correct Answer: D

Rationale: Social support systems involve external sources of support like call-in help lines, emotional assistance from others, and community support groups. These external resources provide individuals with assistance and comfort. Coping skills and verbalization for anger management are personal strategies that individuals use to manage emotions internally. While these skills can be beneficial, they are not considered part of external social support systems.

Correct Answer: D

Rationale: The correct answer is a fresh peach. It is the most suitable snack for a client with sodium restriction as it is naturally low in sodium. Peanut butter cookies (choice A), grilled cheese sandwich (choice B), and cottage cheese and fruit (choice C) contain higher amounts of sodium, making them unsuitable choices for someone on a low-sodium diet. Fresh fruits like peaches are excellent options for individuals on a low-sodium diet as they are not only low in sodium but also provide essential nutrients and hydration.

Correct Answer: B

Rationale: Seeking consensual validation is the correct answer. Consensual validation is a technique used to check one's understanding of what the client has said. It involves confirming with the client whether the nurse's interpretation aligns with the client's feelings or thoughts. This process helps build rapport, trust, and a shared understanding between the nurse and the client. Verbalizing the implied (choice A) refers to expressing the underlying or implicit meaning of a client's statement. Encouraging evaluation (choice C) involves prompting the client to assess or judge a situation. Suggesting collaboration (choice D) entails proposing working together with the client on a shared goal, which is not the primary focus in the scenario provided.

Correct Answer: B

Rationale: The correct answer is B: Denial. The client displaying denial refuses to acknowledge the reality of having a myocardial infarction. Rationalization (choice A) involves making excuses for behavior, not denying a condition. Projection (choice C) is attributing one's thoughts or feelings to others, not denying an illness. Conversion reaction (choice D) is converting psychological distress into physical symptoms, which is not evident in this scenario. Therefore, denial is the defense mechanism being used in this situation.

Correct Answer: A

Rationale: The primary responsibility of the nurse is to take the vital signs before any surgery. This action helps assess the client's baseline condition and identify any abnormalities that need addressing before the procedure. Obtaining the permit (choice B) is typically handled by administrative staff, explaining the procedure (choice C) is usually done by the healthcare provider performing the surgery, and checking the lab work (choice D) is often part of the pre-operative assessment conducted by the healthcare provider. Therefore, in this context, these actions are not the primary responsibility of the nurse.

Correct Answer: B

Rationale: The registered nurse is the correct choice to institute seclusion for a client with schizophrenia. In healthcare settings, only a registered nurse or a physician can legally initiate seclusion. The security guard, licensed practical nurse, and nursing assistant do not have the authority to carry out this action. Therefore, options A, C, and D are incorrect.
