Which of the ff values pertaining to different clients shows the normal range of plasma pH?
- A. 7.35-7.45
- B. 8-Jul
- C. 6.35-6.45
- D. 8.35-8.45
Correct Answer: A
Rationale: The normal range of plasma pH in the human body typically falls between 7.35 and 7.45. This range is necessary to maintain the body's acid-base balance, which is crucial for normal physiological functioning. Deviations from this range can indicate acidosis (pH < 7.35) or alkalosis (pH > 7.45), both of which can have serious health implications. Therefore, option A (7.35-7.45) represents the normal range of plasma pH among different clients.
A nurse is assessing for jaundice in a dark-skinned newborn. Where is the best place to assess for jaundice in this newborn?
- A. Buttocks
- B. Tip of nose and sclera
- C. Sclera, conjunctiva, and oral mucosa
- D. Palms of hands and soles of feet
Correct Answer: C
Rationale: The best place to assess for jaundice in a dark-skinned newborn is in the sclera, conjunctiva, and oral mucosa. Jaundice, which is caused by elevated levels of bilirubin in the blood, is more easily seen in these areas compared to the skin. While jaundice is commonly assessed on the skin in light-skinned individuals, it may not be as readily apparent in dark-skinned newborns. Therefore, examining the sclera, conjunctiva, and oral mucosa for a yellowish discoloration provides a more reliable indication of jaundice in dark-skinned infants. This approach ensures that healthcare providers can accurately detect and monitor jaundice in newborns of all skin tones.
The nurse is taking vital signs of a pregnant woman during her first prenatal visit. The patient asks the nurse if she has to have an HIV test. Which of the following is the nurse's best response?
- A. "Yes, all pregnant women must have the test."
- B. "If you do not have multiple sex partners or inject drugs, it is not necessary."
- C. "Governmental guidelines require an HIV test for all pregnant woman."
- D. "After voluntary pretest counseling, you decide whether HIV testing should be done."
Correct Answer: D
Rationale: The nurse's best response is D, "After voluntary pretest counseling, you decide whether HIV testing should be done." It is important for the pregnant woman to make an informed decision about HIV testing after receiving pretest counseling. The decision should be based on her individual risk factors, concerns, and preferences. The nurse should provide information about the importance of HIV testing during pregnancy, the benefits of knowing one's HIV status, and the available treatment options if the test is positive. Ultimately, the decision should be made by the pregnant woman after considering all the information provided.
A client has had heavy menstrual bleeding for 6 months. Her gynecologist diagnoses microcytic hypochromic anemia and prescribes ferrous sulfate (Feosol), 300mg PO daily. Before initiating iron therapy, the nurse reviews the client's medical history. Which condition would contraindicate the use of ferrous sulfate?
- A. Pregnancy
- B. Ulcerative colitis
- C. Asthma
- D. Severely impaired liver function
Correct Answer: D
Rationale: Severely impaired liver function is a contraindication for the use of ferrous sulfate. In patients with liver disease, iron metabolism can be affected, leading to potential toxicity from iron accumulation. Ferrous sulfate is primarily metabolized by the liver, so in cases of severely impaired liver function, the metabolism of the drug may be altered, leading to potential adverse effects. It is important to consider alternative iron therapy options in patients with severe liver impairment to avoid potential complications.
