One condition or problem that can cause a lack of sensation is

Correct Answer: B

Rationale: The correct answer is B: Diabetes. Diabetes can lead to nerve damage, known as diabetic neuropathy, causing a lack of sensation in the affected areas. High blood sugar levels in diabetes can damage nerves over time, leading to decreased sensation. Constipation (A), hypertension (C), and vomiting (D) do not directly cause a lack of sensation. Constipation is related to bowel movements, hypertension is high blood pressure, and vomiting is a symptom of various conditions, but none of these directly cause a lack of sensation as diabetes does.

Correct Answer: C

Rationale: The correct answer is C: Posture. Posture refers to the way a person holds and positions their body. It encompasses alignment, balance, and positioning of body parts. Pronation (A) is the rotation of the forearm or foot inward. Postpartum (B) is the period after childbirth. Projection (D) refers to attributing one's own unacceptable feelings to others. Therefore, C is the most fitting choice as it directly relates to the description provided in the question.

Correct Answer: C

Rationale: The correct answer is C: Orthostatic. When measuring blood pressure, the first measurement taken is in the orthostatic position, which means the patient is standing or sitting. This initial reading provides a baseline value before any changes due to activity or stress occur. Choice A is incorrect because blood pressure can be measured both when the heart is at work (systolic) and when it is at rest (diastolic). Choice B is incorrect because diastolic pressure is the second measurement taken during blood pressure measurement. Choice D is incorrect because systolic pressure is the second measurement taken during blood pressure measurement.

Correct Answer: C

Rationale: The correct answer is C: Biology. Biology is the study of all life forms, including their structure, function, growth, and evolution. Anatomy (choice A) focuses on the structure of living organisms, while Physiology (choice B) studies the functions of living organisms. Geology (choice D) is the study of the Earth's physical structure and substance, not life forms. Therefore, the correct choice is C as it encompasses the study of all life forms.

Correct Answer: A

Rationale: The correct answer is A because cleaning at least two inches of the catheter near the body helps prevent infection at the insertion site. This step ensures proper hygiene and reduces the risk of catheter-related complications. Rinsing the catheter (choice B) is not as effective as cleaning. Closing the clamp without cleaning (choice C) can lead to bacterial growth. Allowing the clamp to touch the graduate (choice D) can introduce contaminants. Cleaning the catheter near the body is the most essential step in catheter care.
