The practical nurse (PN) is providing care for a client who is receiving an aminoglycoside to treat a bacterial infection.
To assess for signs of ototoxicity, which action should the PN take?
Check for changes in vision.
Monitor the client's hearing.
Observe the skin for a rash.
Measure the urinary output.
The Correct Answer is B
This is the correct answer because it is the best way to assess for signs of ototoxicity, which is a potential adverse effect of aminoglycosides. Ototoxicity is the damage or injury to the inner ear or auditory nerve caused by certain drugs or chemicals. It can result in hearing loss, tinnitus, vertigo, or balance problems. Aminoglycosides are a class of antibiotics that are effective against gram-negative bacteria, but they can also cause ototoxicity by interfering with the function of the hair cells in the cochlea. The practical nurse (PN) should monitor the client's hearing by asking about any changes in hearing acuity, ringing in the ears, or difficulty understanding speech. The PN should also perform a hearing test using a tuning fork or an audiometer if available. The PN should report any signs of ototoxicity to the health care provider and discontinue the aminoglycoside as ordered.
a) Check for changes in vision.
This is not the correct answer because it is not related to ototoxicity. Vision is the ability to see and perceive objects and colors using the eyes and the brain. Vision may be affected by various factors, such as age, genetics, eye diseases, injuries, infections, or medications. However, aminoglycosides do not cause vision problems or impairments. The PN should check for changes in vision in a client who is receiving other drugs that can cause ocular toxicity, such as ethambutol, chloroquine, or digoxin.
c) Observe the skin for a rash.
This is not the correct answer because it is not related to ototoxicity. A rash is a change in the color, texture, or appearance of the skin that may be caused by various factors, such as allergies, infections, inflammation, or medications. A rash may present as redness, itching, swelling, blisters, bumps, or scales.
Aminoglycosides can cause skin reactions such as rash or urticaria in some clients who are hypersensitive or allergic to them. The PN should observe the skin for a rash in a client who is receiving an aminoglycoside and report any signs of an allergic reaction to the health care provider. However, a rash is not a sign of ototoxicity.
d) Measure the urinary output.
This is not the correct answer because it is not related to ototoxicity. Urinary output is the amount of urine produced and excreted by the kidneys and bladder. It is an indicator of renal function and fluid balance. The normal range for urinary output is 0.5 to 1 mL/kg/hour for adults. Urinary output may be affected by various factors, such as fluid intake, dehydration, diuretics, kidney disease, or medications. Aminoglycosides can cause nephrotoxicity, which is another potential adverse effect of these drugs. Nephrotoxicity is the damage or injury to the kidneys caused by certain drugs or chemicals. It can impair the kidneys' ability to filter waste products from the blood, resulting in reduced urine production and oliguria. The PN should measure the urinary output in a client who is receiving an aminoglycoside and report any signs of nephrotoxicity to the health care provider. However, urinary output is not a sign of ototoxicity

Correct Answer is ["B"]
Explanation
The correct answer is Choice B.
Choice A rationale: While notifying the charge nurse about the client’s condition is important, it is not the most critical action. The charge nurse’s role would be to coordinate care and ensure appropriate resources are available, but the immediate safety and well-being of the client and others in the facility is the priority. Therefore, this choice is not the most important action for the nurse to take.
Choice B rationale: Instituting droplet precautions, placing the client in a private room, and keeping the door closed is the most important action. COVID-19 is primarily spread through respiratory droplets when an infected person coughs, sneezes, or talks. It can also be spread by touching a surface or object that has the virus on it and then touching the mouth, nose, or eyes. Therefore, it is crucial to implement droplet precautions to prevent the spread of the virus. This includes wearing a mask, eye protection, and a gown and gloves when caring for the client. The client should also be placed in a private room with the door closed to further prevent the spread of the virus.
Choice C rationale: While it is important for the client to inform others that they may have been potentially exposed, this is not the most critical action. The priority is to prevent the spread of the virus within the healthcare facility. Once the client is appropriately isolated and precautions are in place, the client can be educated and assisted with notifying others about potential exposure.
Choice D rationale: Placing the nasal swab specimen for COVID-19 directly into a biohazard bag is a standard procedure when collecting specimens for testing. However, this action does not address the immediate need to prevent the spread of the virus within the healthcare facility. Therefore, this choice is not the most important action for the nurse to take.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale:
Correcting electrolytes that are out of normal range is a crucial goal of therapy for this client. In diabetic ketoacidosis (DKA), the body’s cells are unable to use glucose for energy due to a lack of insulin. This leads to the breakdown of fat for energy, producing ketones as a by-product. Ketones are acidic and can cause the blood’s pH to decrease, leading to metabolic acidosis. This process also leads to an increased production and excretion of electrolytes such as potassium and sodium. Therefore, correcting these electrolyte imbalances is a key goal of therapy.
Choice B rationale:
While promoting oxygenation to tissues is generally important in critical care, it is not a specific goal in the management of DKA. The primary issues in DKA are metabolic in nature, including hyperglycemia, ketosis, and acidosis.
Choice C rationale:
Preventing hyperventilation is not a specific goal in the management of DKA. Hyperventilation in DKA is a compensatory mechanism for metabolic acidosis (Kussmaul breathing). The body tries to expel more carbon dioxide to reduce the acidity of the blood.
Choice D rationale:
Reversing dehydration is another important goal of therapy for this client. In DKA, high blood glucose levels lead to osmotic diuresis, where water is drawn into the urine from the blood, leading to dehydration. This can cause hypotension and reduced tissue perfusion. Therefore, reversing dehydration through fluid replacement is a key part of treatment.
Choice E rationale:
Replacing insulin is a fundamental goal of therapy for this client. Insulin deficiency is the primary cause of DKA. Insulin allows glucose to enter cells where it can be used for energy, preventing the breakdown of fat for energy and the subsequent production of ketones.
Choice F rationale:
Providing respiratory support may be necessary in severe cases of DKA where the patient’s compensatory respiratory efforts are insufficient to maintain adequate gas exchange. However, it is not one of the primary goals of therapy in DKA management.
