In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?

Correct Answer: B

Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.

Correct Answer: A

Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events. Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications. Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff. Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.

Correct Answer: B

Rationale: The correct answer is 'Knowledge Deficit: New Diabetes Diagnosis.' Newly diagnosed diabetics require education on their disease, medications, glucose testing, insulin injections, foot care, and sick-day plans. Choices A and D aim to prevent issues that do not currently exist for the client. Choice C, 'Alteration in Nutrition: More than Body Requirements,' is not the priority diagnosis for a newly diagnosed diabetic. While nutritional adjustments may be required for type I or type II diabetes, providing knowledge and education takes precedence at this stage.

Correct Answer: C

Rationale: The correct answer is C. Patient confidentiality must be maintained at all times to respect the patient's privacy and dignity. Disclosing sensitive information like a patient's prognosis in a public setting violates confidentiality and can cause distress. The nurse should intervene in this situation and educate the nursing student about the importance of not discussing confidential patient information in public. Choices A, B, and D do not involve breaching patient confidentiality and do not require immediate nurse intervention. Choice A focuses on infection control measures, choice B relates to clinical assessment, and choice D is about the doctor's rounds, which are not urgent matters requiring immediate intervention.

Correct Answer: C

Rationale: The correct answer is that the client has been treated for breast cancer. Combination oral contraceptives containing estrogen and progestin are contraindicated for women with a history of certain conditions, such as thrombophlebitis, thromboembolic disorders, cerebrovascular disease, coronary artery disease, myocardial infarction, known or suspected breast cancer, known or suspected estrogen-dependent neoplasm, benign or malignant liver tumors, and undiagnosed abnormal genital bleeding. Although having type 2 diabetes mellitus, being treated for hypertension, or having hyperlipidemia are risk factors that require caution when using combination oral contraceptives, they are not absolute contraindications like a history of breast cancer.

Correct Answer: B

Rationale: In a situation where a patient describes a brutal assault and rape, the first priority should be to provide emotional support and create a safe and supportive environment. This helps the patient feel secure and cared for, which is crucial for their well-being at that moment. Checking with the case manager about police intervention should come after ensuring the patient's immediate emotional needs are addressed. Cleaning the patient's wounds, though important, can be secondary to providing emotional stabilization. Referring the patient to a counselor specializing in trauma is also crucial for long-term support, but the immediate focus should be on providing emotional support and stability.

Correct Answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

Correct Answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

Correct Answer: D

Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.
