Correct Answer: B

Rationale: The correct answer is B: High-fat diet, smoking, alcohol consumption. These are modifiable risk factors for colorectal cancer as individuals can make lifestyle changes to reduce their risk. Age and gender (choice A) are non-modifiable risk factors. Ethnicity and race (choice C) can influence the risk of colorectal cancer but are not modifiable factors. Exposure to radiation (choice D) is not a common modifiable risk factor for colorectal cancer.

Correct Answer: B

Rationale: The ventrogluteal muscle is the preferred site for intramuscular injections to avoid injury. Choosing the ventrogluteal site reduces the risk of injury to major nerves and blood vessels, unlike the deltoid, rectus femoris, or dorsogluteal sites. The deltoid muscle is commonly used for vaccines but has a higher risk of injury due to its proximity to the radial nerve. The rectus femoris muscle is not recommended for intramuscular injections due to its location and the risk of injury. The dorsogluteal site is also not recommended as it poses a risk of injury to the sciatic nerve and superior gluteal artery.

Correct Answer: B

Rationale: The correct answer is B: Flushed skin. Flushed skin is a common finding in clients with COPD who are experiencing dyspnea. Increased breath sounds (choice A) are not typically associated with COPD; they may indicate conditions like pneumonia. Nasal flaring (choice C) is more commonly seen in respiratory distress in pediatric patients. Decreased respiratory rate (choice D) is not a typical finding in COPD and could indicate respiratory depression.

Correct Answer: C

Rationale: The correct instruction for a client using a metered-dose inhaler (MDI) is to hold the inhaler 1-2 inches from the mouth. This distance allows for the proper delivery of the medication into the lungs. Choice A is incorrect because the duration of inhalation can vary depending on the medication, and 1 second may not be adequate. Choice B is incorrect as shaking the inhaler vigorously is not necessary for all MDIs and can lead to inaccurate dosing. Choice D is incorrect as the client should hold their breath for about 10 seconds after inhalation to allow the medication to deposit in the lungs.

Correct Answer: B

Rationale: The correct answer is 'Increased hematocrit.' In fluid volume deficit (FVD), there is a decrease in the amount of fluid in the blood vessels, leading to hemoconcentration. This results in an increase in hematocrit levels. Choices A, C, and D are incorrect because a decrease in hematocrit, decrease in white blood cell count, and an increase in red blood cell count are not typically seen in fluid volume deficit.
