What is a clinical manifestation of right-sided heart failure?
Wheezing
Vasospasms
Peripheral edema
Tingling in extremities
The Correct Answer is C
Choice A reason: Wheezing is associated with lung conditions or left heart failure, not right-sided heart failure. Peripheral edema results from venous congestion in right heart failure, so this is incorrect.
Choice B reason: Vasospasms are linked to vascular conditions, not right-sided heart failure. Peripheral edema is a hallmark due to fluid backup, so this is incorrect for the manifestation.
Choice C reason: Peripheral edema, swelling in legs or ankles, is a primary manifestation of right-sided heart failure, caused by venous congestion from impaired right heart pumping. This is the correct choice.
Choice D reason: Tingling in extremities is neurological or vascular, not typical of right-sided heart failure. Peripheral edema is more characteristic, so this is incorrect for the manifestation.

Correct Answer is C
Explanation
Choice A reason: The egg would not stay the same size, as ocean water is hypertonic (higher salinity) compared to Lake Michigan’s fresh water. Osmotic differences drive water movement into the egg, causing swelling, making this an incorrect prediction.
Choice B reason: “None of the above” is incorrect, as the egg will swell due to osmosis. Fresh water in Lake Michigan has lower solute concentration than the egg’s cytoplasm, causing water influx, making this an invalid choice.
Choice C reason: The sea star egg will swell in Lake Michigan’s fresh water, which is hypotonic to the egg’s hypertonic cytoplasm. Water moves into the egg via osmosis, increasing its volume, making this the correct prediction for the egg’s response.
Choice D reason: The egg would shrink in a hypertonic environment, like concentrated saltwater, not fresh water. Lake Michigan’s hypotonic fresh water causes water influx, not loss, making shrinking an incorrect outcome for the egg.
Correct Answer is D
Explanation
Choice A reason: Retching is the involuntary attempt to vomit, involving abdominal muscle contractions without expelling stomach contents. The patient is actively expelling contents, which defines vomiting, not just the effort of retching, making this an incorrect term for documentation.
Choice B reason: Expectorate refers to coughing up and spitting out mucus or sputum from the respiratory tract. The patient is expelling stomach contents, not respiratory secretions, making expectorate an incorrect term for this gastrointestinal event.
Choice C reason: Regurgitation is the passive return of undigested food or liquid from the stomach or esophagus, often without force. The forceful expulsion of stomach contents described indicates vomiting, not regurgitation, making this an incorrect documentation term.
Choice D reason: Vomiting is the forceful expulsion of stomach contents through the mouth, driven by coordinated abdominal and diaphragmatic contractions. The patient’s active expulsion into a basin matches this definition, making vomiting the correct term for documentation.
