trazodone (150 mg at bedtime). What is the side effect of trazadone?
A. Sleepiness
B. Pain in the joints
C. Acne breakouts
D. Stuffiness of the nose - Correct Answer-Answer: A. Sleepiness
Trazodone is a serotonin modulator used in the treatment of depression and post-
traumatic stress disorder. It is a serotonin-2 receptor antagonist; thus, it helps in
reducing sleep onset latency and promotes slow-wave sleep. In addition, it can
also block H1 receptors, a mechanism that also contributes to its ability to improve
sleep.

C. High dose aspirin may cause heartburn
D. High dose aspirin may cause the client to have another heart attack - Correct
Answer-Answer: B. High dose aspirin may increase the client's risk of bleeding
Aspirin is a drug with anti-inflammatory and antipyretic effects. It is commonly
given to clients who have recently suffered from a heart attack as it helps prevent
the reoccurrence. However, like all ASAs, aspirin can increase the risk of bleeding in
a client as it allows the blood to be less sticky by altering the clotting factors to be
disrupted.
Thus, the client received a low dose to benefit from the drug while minimizing the
risk of bleeding and altering clotting factors.
A client treated for schizophrenia was prescribed clozapine. What is a major side
effect of clozapine?
A. Sinusitis
B. Dryness of the skin
C. Hypersalivation
D. Muscle pain - Correct Answer-Answer: C. Hypersalivation
Clozapine is an antipsychotic drug. It is commonly used in schizophrenic clients
who are resistant to other medications.
One of its notable side effects is hypersalivation since it is an antagonist of M3
receptors and an agonist at the M4 receptor. M3 blockade and M4 stimulation are
both mechanisms that are known to result in increased salivation.

The neurologist prescribed phenytoin to a client who has been having seizures.
What is a side effect of this drug?
A. Vertigo
B. Sleepiness
C. Gingival overgrowth
D. Malar rash - Correct Answer-Answer: C. Gingival overgrowth
Phenytoin is classified as an anticonvulsant. It is often administered to clients with
complex partial seizures, generalized tonic-clonic seizures, and status epilepticus. It
can prevent and control seizures.
Phenytoin is known to cause gingival hyperplasia, which is also known as gingival
or gum overgrowth. Gingival hyperplasia happens because this drug interacts with
the fibroblasts in the gums resulting in increased collagen production.

A. Reduced motility in the gastrointestinal tract
B. Reduced muscle mass
C. Reduced renal function
D. Reduced liver function - Correct Answer-Answer: D. Reduced liver function

liver damage, the drug will stay in the body for a more extended period due to the
reduced metabolism of the drug. This situation could lead to unwanted side effects
of the drug, and therefore, it should be considered when administering the
medication.

of antibiotics?
A. I can stop the medication once I get better
B. A missed dose should be administered as soon as possible
C. I can take this medication with Tylenol
D. This medication is for my bacterial infection - Correct Answer-Answer: A. I can
stop the medication once I get better
The total dose of antibiotics needs to be taken for the full and long-term effects to
occur. If the client does not finish the entire prescription, they are at risk of
infection reoccurrence.
When a dose is missed, it should be taken as soon as possible to continue
treatment.
There is no contraindication for taking Tylenol with antibiotics.
Antibiotics are generally used to treat bacterial infections. All these statements are
correct.
