A patient is admitted with a fever of 102.8°F (39.3°C), origin unknown. Assessment reveals cloudy, foul-smelling urine that is dark amber in color. Orders have just been written to obtain stat urine and blood cultures and to administer an antibiotic intravenously. The nurse will complete these orders in which sequence?

Choice A reason: Triglycerides are not "good cholesterol." They are lipids stored in adipose tissue or transported in blood, associated with cardiovascular risk when elevated. Unlike HDLs, triglycerides do not remove cholesterol from arteries, making them a risk factor, not a protective lipid in coronary artery disease.

Choice B reason: High-density lipoproteins (HDLs) are known as "good cholesterol" because they transport cholesterol from peripheral tissues to the liver for excretion, reducing arterial plaque buildup. Higher HDL levels are protective against coronary artery disease, making this the correct answer for the patient’s question.

Choice C reason: Very-low-density lipoproteins (VLDLs) transport triglycerides, contributing to atherosclerosis when elevated. They are not considered "good cholesterol," as they do not facilitate cholesterol removal like HDLs. VLDLs are associated with increased cardiovascular risk, unlike the protective role of HDLs.

Choice D reason: Low-density lipoproteins (LDLs) are "bad cholesterol," as they deposit cholesterol in arterial walls, promoting atherosclerosis and coronary artery disease. Unlike HDLs, which remove cholesterol, LDLs increase cardiovascular risk, making this an incorrect choice for "good cholesterol" in laboratory values.

Choice A reason: Penicillin antibiotics, like amoxicillin, inhibit bacterial cell wall synthesis and are not associated with photosensitivity. Their side effects include allergic reactions and gastrointestinal upset. Photosensitivity requires drugs that absorb UV light, altering skin response, which is not a mechanism of penicillin’s action on bacterial peptidoglycan.

Choice B reason: Cephalosporins, similar to penicillins, target bacterial cell walls and are not commonly linked to photosensitivity. Their side effects include hypersensitivity and gastrointestinal issues. Unlike drugs that cause phototoxic reactions by absorbing UV light, cephalosporins lack chromophores that trigger skin photosensitivity, making this incorrect.

Choice C reason: Tetracyclines, like doxycycline, are known to cause photosensitivity by forming phototoxic compounds under UV light exposure. These compounds generate reactive oxygen species, damaging skin cells and causing exaggerated sunburn or rashes. Patients must avoid sun exposure and use sunscreen to prevent this adverse effect during therapy.

Choice D reason: Vancomycin, used for gram-positive infections, inhibits cell wall synthesis but is not associated with photosensitivity. Its primary side effects include nephrotoxicity and red man syndrome. It does not absorb UV light or form phototoxic metabolites, making it an unlikely cause of skin reactions to sunlight.
