Correct Answer: A

Rationale: The correct answer is A, Phlebitis. Phlebitis is the inflammation of a vein, often caused by irritation from an IV catheter, resulting in warmth, redness, and swelling at the site. Infiltration (choice B) refers to the leaking of IV fluids into the surrounding tissues, causing swelling and pallor, not redness and warmth like in the scenario described. An allergic reaction (choice C) would present with itching, hives, or anaphylaxis, rather than localized warmth, redness, and swelling. Fluid overload (choice D) typically manifests as generalized edema, shortness of breath, and weight gain, not localized symptoms at the IV site.

Correct Answer: B

Rationale: The most important instruction for a client with tuberculosis (TB) is to take all prescribed medications as directed. This is crucial to prevent the development of drug-resistant TB. While avoiding close contact with others until treatment is complete (Choice A) is important to prevent the spread of TB, ensuring the client completes the prescribed medication regimen is the priority. Scheduling a follow-up appointment (Choice C) is important for monitoring but not as critical as medication adherence. Wearing a mask in public places (Choice D) can help reduce the spread of TB but is not as essential as taking medications as prescribed.

Correct Answer: C

Rationale: Tingling around the mouth is the most concerning finding as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common due to surgical manipulation, slight swelling at the incision site is expected postoperatively, and mild fever can be a normal inflammatory response. Hypocalcemia after thyroidectomy can lead to serious complications and should be addressed promptly to prevent further issues.

Correct Answer: B

Rationale: The cervix functions in reproduction by secreting mucus that facilitates the transport of sperm to the uterus. Choice A is incorrect because the cervix does not interpret signals of sexual stimuli. Choice C is incorrect as the site for the union of ovum and sperm is the fallopian tube. Choice D is incorrect as the cervix is not involved in receiving the penis during intercourse.

Correct Answer: C

Rationale: The correct answer is C: 'Nervousness and tremors.' In a client with hypothyroidism prescribed levothyroxine, the development of nervousness and tremors may indicate hyperthyroidism, which can result from excessive dosing of levothyroxine. Therefore, the nurse should promptly notify the healthcare provider to adjust the medication dosage. Choices A, B, and D are incorrect because weight gain, bradycardia, and fatigue are more commonly associated with hypothyroidism itself, indicating that the levothyroxine therapy may not be effective enough, rather than being signs of excessive dosing.
