Accepted Answer

A,B,C,D

Question 2

A client is diagnosed with enterobiasis.The nurse recognizes the primary symptom of enterobiasis as:

Accepted Answer

The primary symptom of enterobiasis is perianal itching, especially at night. Other symptoms may include abdominal pain, nausea, and diarrhea, but these are less common. An erythematous rash on the chest and body is not typically seen with enterobiasis, nor is a chronic cough with sweating at night.

Question 3

The nurse is caring for a client with a protozoan infection.The nurse instructs the client that the growing stage of a protozoan is termed a:

Accepted Answer

The growing stage of a protozoan is termed a trophozoite. A cyst is a dormant or resting stage of a protozoan, while a worm refers to a different type of organism entirely. A vector is an organism that carries and transmits a pathogen, but is not a stage in the life cycle of the pathogen itself.

Question 4

The nurse would correctly understand that pharmacotherapy of cryptosporidiosis is targeted at treating:

Accepted Answer

Cryptosporidiosis is an infection that commonly causes diarrhea. Therefore, the primary focus of pharmacotherapy is to treat diarrhea and control symptoms.

Question 5

A client has been hospitalized with malaria.The nurse explains to a family member that the primary determining factor for drug selection with this disease process is:

Accepted Answer

The answer of A client has been hospitalized with malaria.The...

Question 6

The nurse treating a client with malaria knows that the goals of pharmacotherapy include: Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The goals of pharmacotherapy for malaria include chemoprophylaxis to prevent the disease from occurring in the first place, treatment of acute attacks to control symptoms and clear the infection, and prevention of relapses by eliminating any remaining parasites in the body. There is no indication that malaria increases the risk of bacterial or viral infections, so options D and E are incorrect.

Question 7

The nurse is caring for a client suspected of having a protozoan infection of the intestines.The nurse knows that which protozoan infections are spread by poor sanitation? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

Amebiasis, giardiasis, and cryptosporidiosis are all protozoan infections that can be spread by poor sanitation, such as contaminated water sources or insufficient hygiene practices. Toxoplasmosis is typically spread through ingestion of contaminated meat or contact with infected cat feces, while trichomoniasis is a sexually transmitted infection.

Question 8

When oral mebendazole (Vermox)is prescribed for the treatment of ascariasis,the nurse would expect the drug regimen to be administered:

Accepted Answer

The answer of When oral mebendazole (Vermox)is prescribed for the...

Question 9

What drug would the nurse expect to be the first choice of drugs ordered during the chemoprophylaxis stage in the treatment of malaria?

Accepted Answer

Chloroquine is the first choice drug for chemoprophylaxis in the treatment of malaria due to its effectiveness, low cost, and ease of administration. However, it is important to note that the choice of drug may depend on the geographical location of the patient and the prevalence of resistant strains of malaria in that region.

Question 10

The nurse caring for a client with amebiasis explains that although other forms of transmission are possible,amebiasis is primarily acquired through:

Accepted Answer

Amebiasis is primarily acquired through ingestion of contaminated food or water. Other forms of transmission, such as blood transfer or respiratory droplets, are possible but less common. Open sores are not a known mode of transmission for amebiasis.

Question 11

The nurse is teaching a pharmacology course when a student comments that bacteria and protozoans are alike.The nurse would be correct in noting that,in contrast to bacteria,protozoans:

Accepted Answer

Protozoans go through maturation stages in the host, while bacteria do not. This is a key difference between the two types of microorganisms. While both can cause disease, protozoans are often more complex in their lifecycle and may require different types of treatment compared to bacteria.

Question 12

The nurse is providing education to a client with malaria.When the client asks about the relationship between the life cycle of the Plasmodium and treatment of malaria,the nurse bases the answer on which concept?

Accepted Answer

The life cycle of the Plasmodium is disrupted by the drug choice. Malaria parasites have a complex life cycle, and different drugs work at different stages of the life cycle. For example, drugs such as chloroquine, quinine, and mefloquine work by disrupting the parasite's ability to replicate in the bloodstream, while primaquine targets the parasite in the liver. Therefore, understanding the life cycle and choosing the appropriate drug is crucial in the treatment of malaria.

Question 13

The nurse asked to identify the most likely infestation site of helminths would be correct in identifying the:

Accepted Answer

Helminths commonly infest the gastrointestinal tract and therefore the intestine is the most likely infestation site. The lungs may be affected by some helminths, but it is less common. Infestation of the eyes or feet by helminths is very rare.

Question 14

The nurse caring for a client diagnosed with amebiasis understands that amebiasis is best treated with:

Accepted Answer

The answer of The nurse caring for a client diagnosed...

Question 15

The nurse is providing chemoprophylaxis drug therapy for a client who will be traveling to a country with a high incidence of malaria.Which drugs are appropriate for chemoprophylaxis? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

Chloroquine, Atovaquone-proguanil, and Primaquine are appropriate for malaria chemoprophylaxis. Chloroquine is used in areas with chloroquine-sensitive malaria. Atovaquone-proguanil is a choice for areas with chloroquine-resistant strains. Primaquine can be used for the radical cure of P. vivax and P. ovale by clearing hepatic gametocytes, and also for prophylaxis in certain circumstances. Artemether-lumefantrine and Quinine sulfate are typically used for treatment rather than prophylaxis.

Question 16

Following treatment with praziquantel (Biltricide)for tapeworm infestation,the nurse would expect to administer:

Accepted Answer

Praziquantel works by paralyzing the tapeworms, causing them to detach from the intestinal wall and be excreted in the feces. This can cause blockages in the digestive tract and potentially lead to obstruction. Administering a laxative after treatment can help to ensure that the tapeworms are fully eliminated from the body. Yogurt, antacids, and liquid diets are not necessary after treatment with praziquantel for tapeworm infestation.

Question 17

What information should the nurse provide to the parents of a child being treated for enterobiasis (pinworms)?

Accepted Answer

Everyone in the household should be treated for enterobiasis (pinworms) because the eggs are easily spread among family members.

Question 18

The nurse caring for a client with giardiasis expects the client to have symptoms that primarily affect the:

Accepted Answer

Giardiasis is an infection caused by the parasitic protozoan Giardia lamblia. The primary symptoms of giardiasis affect the gastrointestinal system, including diarrhea, abdominal cramping, bloating, and nausea.

Question 19

The nurse is educating a client on how protozoan infections are spread.The client asks if the infection is similar to a bacterial infection.To help distinguish the infections,what information regarding vectors does the nurse plan to include in the education session? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The answer of The nurse is educating a client on...

Question 20

A client has been diagnosed with trichomoniasis.The nurse expects the client to exhibit symptoms in the:

Accepted Answer

Trichomoniasis is a sexually transmitted infection that affects the reproductive system, causing symptoms such as vaginal discharge, itching, and inflammation. It does not typically affect other systems, such as the gastrointestinal, integumentary, or respiratory systems.
