When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

Correct Answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

Correct Answer: A

Rationale: When assessing a client with a cast, it is crucial to check for capillary refill to ensure adequate circulation. Warm toes indicate good circulation, while the absence of discomfort suggests the cast is not causing any pain or undue pressure on the client. Therefore, choices B, C, and D are incorrect as they do not address the essential components of assessing a client with a cast.

Correct Answer: B

Rationale: The first action the nurse should take is to report the finding to the nursing supervisor and follow the chain of command. Notifying the nursing supervisor allows for immediate action within the facility to address the discrepancy. If it is found that the pharmacy is in error, then notifying the hospital pharmacist (Choice A) would be appropriate. Choices C and D, notifying the Board of Nursing and the director of nursing, are not the initial steps to take. These options may be necessary if theft is suspected or if the facility's internal response is inadequate. Therefore, they are incorrect answers.

Correct Answer: A

Rationale: In this situation, the best approach for the nurse is to ask whether another individual wants to be the client's support person. This empowers the client to choose someone to be with her until her family can join her, providing the needed support and comfort. Assuring her that a nursing staff member will be with her at all times (Choice B) may not fully address her emotional needs for familiar support. Telling her you will try to locate her family (Choice C) may not be feasible in the immediate situation and may not provide immediate emotional support. While reinforcing the woman's confidence in her own abilities (Choice D) is important, it may not fully address her current need for emotional support and presence of a companion.

Correct Answer: B

Rationale: Individual state laws mandate the reporting of infectious diseases. The list of reportable diseases varies from state to state and is overseen by state health departments. While the CDC plays a significant role in disease surveillance, reporting infectious diseases is primarily governed by individual state laws. The CDC's role is to provide support, guidance, and expertise to state health departments. The National Institutes of Health (NIH) primarily focus on biomedical and health-related research, not on mandating disease reporting. Health and Human Services (HHS) is a federal department that oversees various agencies, but the responsibility for mandating disease reporting lies with individual states.

Correct Answer: A

Rationale: Informed consent is a person's agreement to allow something, such as a treatment, to be performed. A consent form is required even if the problem is a sexually transmitted infection. If the client is a minor, the minor may sign the informed consent form in specific situations, including seeking treatment for a sexually transmitted infection. In this case, the 17-year-old client is seeking examination and treatment for a sexually transmitted infection, so she will need to sign the informed consent form. Contacting her parents for permission is not required in this situation. Choice C is incorrect because a consent form is necessary regardless of the medical issue. Choice D is incorrect because the individual's age is not the determining factor; rather, it is the nature of the medical service being sought that dictates the need for informed consent.

Correct Answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.

Correct Answer: B

Rationale: The correct answer is to promote healthy nutritional practices. This goal focuses on preventive measures to address the client's nutritional risk. Providing oxygen (Choice A) is not directly related to addressing nutritional problems. Treating complications of malnutrition (Choice C) involves addressing the consequences rather than preventing or managing the nutritional problems. Increasing weight (Choice D) would only be appropriate if the client is underweight; it does not address the broader aspect of promoting overall healthy nutritional practices.

Correct Answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.
