Which laboratory test would be the least effective in diagnosing a myocardial infarction?

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: B

Rationale: The correct answer is 'an individual's relationship with a higher power.' Spirituality is more about personal connection, beliefs, and experiences related to a higher power or force, whereas religion is often associated with organized practices, rituals, and doctrines within a specific faith community. Choice A is incorrect as spirituality goes beyond just believing in a higher power; it encompasses a personal connection. Choice C, 'organized worship,' is incorrect because spirituality can exist outside formal religious settings. Choice D is incorrect as it oversimplifies spirituality as merely a belief in an invisible energy or ideal, missing the relational aspect with a higher power.

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: A

Rationale: When a client reports talking to voices, the nurse should engage in a gentle touch to help the client return to reality. It is important for the nurse to acknowledge the client's experience and attempt to redirect them gently. Touch can provide grounding and connection. Asking the client to describe what is happening can be overwhelming and might exacerbate the situation. Leaving the client alone may not be safe or therapeutic as the client may need support. Telling the client there are no voices denies their reality and is not helpful in managing their experience.

Correct Answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.

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 correct answer is to decrease the stimuli in the home. The wife's behavior suggests obsessive-compulsive disorder, an anxiety disorder. By reducing stimuli in the environment, such as clutter or triggers that prompt cleaning, it helps in managing the condition and promoting a calmer atmosphere. Option A is incorrect as directly telling the wife to stop can escalate her anxiety. Option B is not the priority initially, as addressing the root cause is more crucial. Option D may reinforce the behavior rather than addressing the underlying issue.

Correct Answer: B

Rationale: In a client with severe burns to the face and neck, airway assessment and supplemental oxygen are crucial. Therefore, applying oxygen is the priority to ensure adequate oxygenation for the client. This intervention takes precedence over other actions to stabilize the client's condition. Starting an IV for fluid resuscitation is the next appropriate step following ensuring oxygenation (Choice A). While pain management is important, it is a secondary priority after ensuring oxygenation and fluid resuscitation, making medicating the client for pain a later intervention (Choice D). Obtaining blood gases (Choice C) is not the immediate priority in this scenario and would typically be ordered by the healthcare provider based on the client's condition and response to initial interventions.

Correct Answer: D

Rationale: The correct answer is 'Clear-liquid.' After a hemorrhoidectomy, the client is usually started on a clear-liquid diet to allow the intestines to rest and promote healing. This diet helps prevent straining during bowel movements, which is crucial for recovery. Stool softeners are often included in the plan to avoid constipation. Once the client tolerates the clear liquids well, they can progress to a regular diet. High-fiber diet (choice A) is beneficial in the later stages of recovery to prevent constipation but is not typically the initial post-operative diet. Low-residue diet (choice B) and bland diet (choice C) are not appropriate for this type of surgery as they may not provide the necessary post-operative care and support needed for healing.
