Other signs of hypovolemia includes all of the following except:

Correct Answer: A

Rationale: When assessing for signs of hypovolemia, dry mucous membranes and soft eyeballs are actually indicative of dehydration, not specifically hypovolemia. In hypovolemia, the body loses both fluid and electrolytes, leading to decreased circulating blood volume. Other signs of hypovolemia include increased hematocrit and hemoglobin levels due to hemoconcentration, decreased pulse rate and widened pulse pressure as compensatory mechanisms to maintain perfusion to vital organs, and increased lethargy and confusion due to impaired perfusion to the brain.

Correct Answer: B

Rationale: Potassium is an essential mineral that plays a key role in numerous bodily functions, including muscle contractions and maintaining proper heart function. Among the options given, potatoes are an excellent source of potassium. One medium-sized potato can provide around 900 mg of potassium, making it a great choice for individuals who need to increase their potassium intake. Therefore, potatoes are recommended for the patient who must increase their intake of potassium.

Correct Answer: C

Rationale: A hypertonic solution has a higher concentration of solutes compared to the intracellular fluid. In this case, 5% dextrose in 0.9% NaCl is hypertonic because it has a higher osmolarity due to the combined effect of dextrose and sodium chloride. The dextrose contributes to the hypertonicity, making the overall solution more concentrated than the intracellular fluid.

Correct Answer: B

Rationale: In this question, option B, "Crowded living conditions," is the correct answer as it is not a recognized risk factor for lung cancer. Exposure to passive smoke (Option A) is a well-established risk factor for lung cancer as it exposes individuals to harmful carcinogens. Air pollution (Option C) also increases the risk of developing lung cancer due to the inhalation of toxic particles. A diet low in fruits and vegetables (Option D) can contribute to an increased risk of lung cancer as these foods are rich in antioxidants and nutrients that help protect against cancer development. Educationally, it is important for students to understand the various risk factors associated with lung cancer to educate patients effectively. By knowing the correct risk factors, healthcare providers can offer tailored advice on prevention strategies. Recognizing the role of environmental exposures and dietary habits in lung cancer development is crucial in promoting health and wellness.

Correct Answer: B

Rationale: Rifampin is a medication known to cause harmless discoloration of bodily fluids, including tears and sweat. This discoloration can also affect contact lenses if worn by the individual taking rifampin. Therefore, it is important for the nurse to inform clients who are prescribed rifampin about this potential side effect to prevent any concerns or misunderstandings. It is advisable for clients to use glasses instead of contact lenses while taking rifampin to avoid this discoloration.
