Question 1 of 5
Which condition can result from prolonged vomiting or diarrhea?

Question 3 of 5
Which electrolyte is important in the formation of the thyroid hormones?
Correct Answer: B
Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.
Question 4 of 5
The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?
Correct Answer: B
Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage.
Therefore, option B is the correct choice as it aligns with best practices for IV insertion.
Question 5 of 5
You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patient's skin turgor?
Correct Answer: C
Rationale: Inelastic skin is a normal change of aging. However, this does not mean that skin turgor cannot be assessed in older patients. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy.
Choice A is incorrect because overhydration is not common among healthy older adults.
Choice B is incorrect because dehydration leads to inelastic skin, not sponginess.
Choice D is incorrect as skin turgor assessment can be done in patients of any age, including those over 70.
