A nurse is assessing a client who has hyperthyroidism. The nurse should expect the client to report which of the following manifestations?

A.

Constipation

B.

Sensitivity to cold

C.

Weight gain of 4.5 kg (10 lbs) in 3 weeks

D.

Frequent mood changes

Answer and Explanation

The Correct Answer is D

Choice A Reason:

 

Constipation is not typically associated with hyperthyroidism. Hyperthyroidism usually speeds up the body’s metabolism, leading to symptoms like increased bowel movements or diarrhea rather than constipation.

 

Choice B Reason:

 

Sensitivity to cold is more commonly associated with hypothyroidism, where the body’s metabolism slows down. In hyperthyroidism, patients often experience heat intolerance due to an increased metabolic rate.

 

Choice C Reason:

 

Weight gain of 4.5 kg (10 lbs) in 3 weeks is also more indicative of hypothyroidism. Hyperthyroidism generally causes weight loss despite an increased appetite because of the accelerated metabolism.

 

Choice D Reason:

 

Frequent mood changes are a common symptom of hyperthyroidism. The excess thyroid hormones can affect the nervous system, leading to symptoms such as anxiety, irritability, and mood swings.

Correct Answer is B

Explanation

Choice A: Smallpox

Smallpox is a viral disease caused by the variola virus. It was eradicated globally in 1980 through a successful vaccination campaign. Treatment for smallpox primarily involves supportive care and antiviral medications, such as tecovirimat, rather than antibiotics like ciprofloxacin. Ciprofloxacin is ineffective against viral infections, including smallpox.

Choice B: Anthrax

Anthrax is a serious infectious disease caused by the bacterium Bacillus anthracis. Ciprofloxacin is one of the primary antibiotics used for the treatment and post-exposure prophylaxis of anthrax. It works by inhibiting bacterial DNA gyrase, which is essential for bacterial replication. Ciprofloxacin is effective against both cutaneous and inhalational forms of anthrax, making it a critical component in the management of anthrax exposure.

Choice C: Ebola virus

Ebola virus disease (EVD) is caused by the Ebola virus, a member of the Filoviridae family. Treatment for EVD primarily involves supportive care, including rehydration and management of symptoms. Antiviral medications, such as remdesivir, may also be used. Ciprofloxacin, being an antibiotic, is not effective against viral infections like Ebola.

Choice D: Sarin gas

Sarin gas is a highly toxic nerve agent used in chemical warfare. Exposure to sarin gas requires immediate medical intervention, including the administration of antidotes such as atropine and pralidoxime, as well as supportive care. Antibiotics like ciprofloxacin are not used in the treatment of chemical agent exposure, as they do not counteract the effects of nerve agents.

Correct Answer is B

Explanation

Choice A reason:

Intense pruritus: While itching (pruritus) can be a symptom of skin conditions, it is not a definitive sign of malignancy in nevi. Pruritus can be associated with benign conditions such as eczema or allergic reactions. However, if a mole starts to itch, it should be monitored closely, but it is not as strong an indicator of malignancy as irregular borders.

Choice B reason:

Irregular borders: This is a significant sign of potential malignancy in nevi. Melanomas often have uneven, notched, or scalloped borders, unlike benign moles, which typically have smooth, even borders. The irregularity in the border is due to the uncontrolled growth of melanocytes, which can spread unevenly.

Choice C reason:

Uniform pigmentation: Uniform pigmentation is generally a sign of a benign mole. Malignant moles often have multiple colors or an uneven distribution of color, which can include shades of brown, black, red, white, or blue. A mole with uniform color is less likely to be malignant.

Choice D reason:

Purulent drainage: While purulent drainage (pus) indicates an infection, it is not a typical sign of malignancy in nevi. Infections can occur in any skin lesion, but they do not specifically indicate cancer. Malignant moles are more likely to change in size, shape, or color rather than produce pus.
