Adult Health Exam 1 Chamberlain

Correct Answer: C

Rationale: Shortness of breath is a characteristic symptom of left-sided heart failure. In this condition, the heart's inability to effectively pump blood forward causes blood to back up into the lungs, leading to fluid accumulation. This fluid accumulation results in pulmonary congestion, manifesting as shortness of breath or difficulty breathing. Peripheral edema (choice A) is more commonly associated with right-sided heart failure, where fluid accumulates in the extremities. Jugular vein distention (choice B) is a sign of increased central venous pressure and is more indicative of right-sided heart failure. Weight gain (choice D) can be a general symptom of heart failure due to fluid retention, but shortness of breath is specifically related to left-sided heart failure.

Correct Answer: C

Rationale: The ventrogluteal site is preferred for intramuscular injections in adults due to its muscle mass and lower risk of nerve injury. The deltoid muscle is more commonly used for vaccines in adults, the vastus lateralis muscle is preferred in infants and young children, and the dorsogluteal muscle is associated with a higher risk of nerve injury and is no longer recommended for intramuscular injections.

Correct Answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

Correct Answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.

Correct Answer: C

Rationale: Tingling around the mouth should be reported to the healthcare provider immediately as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common postoperatively due to surgical manipulation, slight swelling at the incision site is a normal response, and a mild fever can be expected after surgery. However, tingling around the mouth suggests a potential calcium imbalance, which requires prompt attention to prevent serious complications.
