A patient arrives at the clinic for his yearly physical. His vital signs include a blood pressure of 170/110. The patient is prescribed an ACE (angiotensin-converting enzyme) inhibitor. This medication decreases blood pressure by inhibiting the
vasoconstrictive properties of the RAAS (renin-angiotensin-aldosterone system)
vasodilation properties of the RAAS
inotropic properties of the sympathetic nervous system (SNS)
diuretic properties of the natriuretic peptide system
The Correct Answer is A
A. ACE inhibitors block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor in the RAAS, which leads to decreased blood pressure by promoting vasodilation.
B. The RAAS is primarily a vasoconstrictive system, and ACE inhibitors reduce this vasoconstriction, not vasodilation.
C. ACE inhibitors do not directly affect the inotropic (force of contraction) effects of the SNS; they work on the RAAS.
D. While natriuretic peptides help regulate fluid balance, ACE inhibitors do not directly impact this system.

Correct Answer is C
Explanation
A. A specific gravity of 1.000 indicates very dilute urine, not concentrated. This would not be typical of dehydration, where urine would be concentrated with a high specific gravity.
B. Acute kidney injury (AKI) typically results in more concentrated urine due to retained waste products; therefore, specific gravity would likely be higher, not at the minimum level of 1.000.
C. A specific gravity of 1.000 indicates the kidney’s inability to concentrate urine, often seen in renal impairment where kidney function is compromised, leading to very dilute urine.
D. Specific gravity is unrelated to testicular cancer or an undescended testis, as it measures kidney concentration ability rather than reproductive health.
Correct Answer is D
Explanation
A. Prostate cancer is unlikely to cause burning on urination or costovertebral tenderness; it usually presents with urinary obstruction symptoms or systemic effects.
B. Ureteral lithiasis may cause burning on urination but is more typically associated with flank pain rather than constant costovertebral tenderness.
C. Primary syphilis does not typically present with urinary symptoms or costovertebral tenderness.
D. Pyelonephritis, an infection of the kidney, commonly presents with burning on urination, fever, and costovertebral angle tenderness, indicating inflammation and infection of the renal pelvis and kidneys.
